Answer:
x = 9
Step-by-step explanation:
An exterior angle of a triangle is equal to the sum of the opposite interior angles.
Here the exterior angles has a measure of 10x + 58° while its opposite interior angles have measures of 6x + 56° and 38°
If an exterior angle of a triangle is equal to the sum of the opposite interior angles then 10x + 58 = 6x + 56 + 38
we now solve for x
10x + 58 = 6x + 56 + 38
==> combine like terms
10x + 58 = 6x + 94
==> subtract 58 from both sides
10x = 6x + 36
==> subtract 6x from both sides
4x = 36
==> divide both sides by 4
x = 9
and we are done! :)
Answer:
x = 9
Step-by-step explanation:
The sum of all the interior angles of a triangle = 180 degrees
one of the angles of the triangle's interior is blank, so to find it we can subtract the exterior angle measure next to it from 180 degrees (a straight line)
38 + (6x + 56) + (180 - (10x + 58)) = 180
Now, we can do our best to simplify and combine like terms:
[38 + 56 + (180 - 58)] + [6x - 10x] = 180
216 - 4x = 180
Now we can subtract 180 from both sides...
36 - 4x = 0
And then add 4x to both sides...
36 = 4x
Now we've manged to isolate x, all that's left is to divide both sides by 4
9 = x
Or
x = 9

The length of a rectangle is 7 more than the width. The area is 744 sqaure yards, find the length and width of the rectangle
Answers
Answer:
Length of rectangle is 31 yards and Width is 24 yards.
Given:
The length of a rectangle is 7 more than the width. The area is 744 sqaure yardsSolution:
Let's assume Width of rectangle be x and Length of rectangle be x + 7 respectively.
Using formula
[tex] \\ \: \: \: \: \pink{ \dashrightarrow \: \: \: \: \sf { \underbrace{Area_{(Rectangle)} = Length × Width }}} \\ \\ [/tex]
On Substituting the required values, we get;
[tex]\\ \: \: \: \: \dashrightarrow \: \: \: \: \sf (x)(x + 7) = 744 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf {x}^{2} + 7x = 744 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf {x}^{2} + 7x - 744 = 0 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf {x}^{2} + 31x - 24x - 744 = 0 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf x(x + 31) - 24 (x + 31) = 0 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf (x + 31)(x - 24) = 0 \\ \\ \\ \: \: \: \: \dashrightarrow \: \: \: \: \sf x = 24 \: or \: - 31 \\ \\ [/tex]
As we know that width of the rectangle can't be negative. So x = 24
Hence,
Width of rectangle = x = 24 yardsLength of the rectangle = x + 7 = 31 yards[tex] \therefore[/tex]Length of rectangle is 31 yards and Width is 24 yards.

We can solve for angle HKG by using supplementary angles. The angle next to it and itself will add up to 180 degrees, as they are on a straight line.
[tex]120 + ?=180[/tex]
[tex]?=60[/tex]
Angle HKG is 60 degrees.
---
Now, we also know that in triangles, the angles are 180 degrees. We can add up all the angles and find x:
[tex]60+(6x-10)+(2x+10)=180[/tex]
Remove parenthesis:
[tex]60+6x-10+2x+10=180[/tex]
Add like terms:
[tex]8x+60=180[/tex]
Subtract 60 from both sides:
[tex]8x=120[/tex]
Divide both sides by 8:
[tex]x=15[/tex]
PROBLEM NUMBER TWOWe have more supplementary angles. We can find angle JHG:
[tex]?+72=180[/tex]

---
Now add up the interior angles of the triangle:
[tex]4x-2+3x+4+108=180[/tex]
Add like terms:
[tex]7x+110=180[/tex]
Subtract 110 from both sides:
[tex]7x=70[/tex]
Divide both sides by 7:
[tex]x=10[/tex]
PROBLEM NUMBER TWOWe have more supplementary angles. We can find angle BDC:

Now add up the interior angles of the triangle:

Subtract 60 from both sides:

Rina Botwright receives $624 gross salary biweekly. Her income tax rate is 14%. Her group health plan contribution is $4.25 per pay period. She belongs to the company retirement plan, to which she contributes 6% of her earnings. She is also covered under Social Security benefits. Her current contribution is 6.05%
If these items are all her deductions, what is her take-home pay per period?
Rina gets a $35 raise per pay period. If her health plan is unchanged, how much of the raise will she have to take home?
take-home pay per period = $
amount of raise taken home = $
Answers
Rina Take home pay is $457.20
what is Salary percentage?
The basic salary divided by the Gross salary is multiplied by 100. The result is the percentage of gross salary.
Given that:
gross salary = $624
14% income tax = 624* 0.14 = $87.36
group health plan = $4.25
Company retirement = 624 * 0.060 =$37.44
Social Security = 624 * 0.0605 = $37.752
Home pay= 624 - 87.36 - 4.25 - 37.44- 37.752
= 457.198
Her take home pay is $457.198
if she gets a $35 raise per pay period,
So, new gross salary would be,
= $624 + $35
= $659.
Again, we have
14% Income tax = 659 * 0.14 = $92.26
Group health plan = $4.25
Company retirement = 659 * 0.060 = $39.54
Social Security = 695* 0.0605 = $39.8695
Home take pay,
=659-39.8695 - 45.825 - 39.54-92.26
=441.5055
Her take home pay is $441.5055

Answer:
z = 7/3 is extraneous.
Step-by-step explanation:
√(z^2+8) = 1 - 2z
z^2 + 8 = (1 - 2z)^2
z^2 + 8 = 1 -4z + 4z^2
3z^2 - 4z - 7 = 0
3z^2 + 3z - 7z - 7 = 0
3z(z + 1) - 7(z + 1) = 0
(3z - 7)(z + 1) = 0
3z = 7, z = -1
z = 7/3, -1.
One of these might be extraneous.
Checking:
√(z^2+8) = 1 - 2z, if z = -1:
√(1 + 8) = 3, -3
1 - 2(-1) = 3. So its not z = -1
if z = 7/3
√((7/3)^2 + 8) = 13.44
1 - 2(7/3) = -3.66
So its z = 7/3
Answer:
[tex]z=\dfrac{7}{3}[/tex]
Step-by-step explanation:
Given equation:
[tex]\sqrt{z^2+8}=1-2z[/tex]
Square both sides:
[tex]\implies (\sqrt{z^2+8})^2=(1-2z)^2[/tex]
[tex]\implies z^2+8=1-4z+4z^2[/tex]
Subtract [tex]z^2[/tex] from both sides:
[tex]\implies 8=1-4z+3z^2[/tex]
Subtract 8 from both sides:
[tex]\implies 0=-7-4z+3z^2[/tex]
[tex]\implies 3z^2-4z-7=0[/tex]
Rewrite the middle term:
[tex]\implies 3z^2+3z-7z-7=0[/tex]
Factor the first two terms and the last two terms separately:
[tex]\implies 3z(z+1)-7(z+1)=0[/tex]
Factor out the common term [tex](z+1)[/tex]:
[tex]\implies (3z-7)(z+1)=0[/tex]
Therefore:
[tex]\implies (z+1)=0 \implies z=-1[/tex]
[tex]\implies (3z-7)=0 \implies z=\dfrac{7}{3}[/tex]
To find the extraneous solution (the root that is not a root of the original equation), enter the two found values of z into the original equation:
[tex]\begin{aligned}z=-1\implies \sqrt{(-1)^2+8}&=1-2(-1)\\\implies 3&=3\implies \textsf{true}\\\end{aligned}[/tex]
[tex]\begin{aligned}z=\dfrac{7}{3} \implies \sqrt{\left(\frac{7}{3}\right)^2+8}&=1-2\left(\frac{7}{3}\right)\\\implies \dfrac{11}{3} &=-\dfrac{11}{3}\implies \textsf{false}\end{aligned}[/tex]

In the parallelogram above, if angle R is 56 degrees, what is the value of x + y?
Answers
Answer:
248
Step-by-step explanation:
Consecutive angles of a parallelogram are supplementary.
56 + y = 180
y = 180-56
y =124
The opposite angles of a parallelogram are equal.
x = y = 124
x+y = 124+124
=248
Answer:
x + y = 248
Step-by-step explanation:
consecutive angles in a parallelogram sum to 180°
opposite angles are congruent
x + 56° = 180° ( subtract 56° from both sides )
x = 124°
then
y = x = 124 , so
x + y = 124 + 124 = 248
