In the triangle shown ,AB =2x +9 and BC=5x–12. Find the value of x.
show how you go the answer so I can see if it makes sense!!!
Answers
2x +9 = 5x -12
(Now bring the x to the left, and rest to the right)
2x -5x = -12 -9
(Solve this)
-3x = -17
Then
: -3 to get x
So -17 : -3 u get 5.67
So
x = 5.67
(I think this would be the answer, if I’m wrong, I’m really sorry)
Answer:
In the given triangle, AB=BC
Now, 2x+9=5x-12
=> 5x-2x=12+9
=> 3x=21
=> x=21/3
=> x=7
Therefore, the value of x is 7.
What is the answer for 76 = -4b
Answers
Answer:

Divide each side by -4
76/-4 = 4-b/-4
-19 = b
Answer:
b = -19
Step-by-step explanation:
76 = -4b
shift -4 to the left hand side and when you shift -4 divides 76
76/-4 = b

ZC and Dare vertical angles.
m_C=° and mZD=(-3x +80)°
What is mZC
Enter your answer in the box.
Answers
Answer:
M<C = 20°
Step-by-step explanation:
Because they’re vertical angles, that means they’re equal to each other so:
m<C = m<D
x = -3x + 80
x + 3x = 80
4x = 80
x = 20
Since m<C equals x, that means m<C is 20°

Given,
HK is the perpendicular bisector of GJ. So, GK = KJ.GK = 2x + 10KJ = 3x - 15_______________
Find KJ .

Hope it helps.
RainbowSalt2222
Answer:
KJ = 60
Step-by-step explanation:
In order to find the length of KJ we must find the value of x
Perpendicular bisectors split lines into two EQUAL parts.
If GJ is bisected then the two parts that make it up are equal to each other.
In other words GK = KJ
If GK = 2x + 10 and KJ = 3x - 15 then
2x + 10 = 3x -15
Solve for x
2x + 10 = 3x -15
Subtract 2x from both sides
10 = x - 15
Add 15 to both sides
x = 25
Now to find KJ we simply plug in the value of x into KJ's given expression
Expression given: 3x - 15
x = 25
KJ = 3(25) - 15
Multiply 3 and 25
KJ = 75 - 15
Subtract
KJ = 60

write the formula for the area of a triangle, A = 1/2bh in terms of h. Find the height of a triangle when A = 18 in.² and b = 9 in. Please give explanation thank you :)
Answers
Answer:
2A/b = h
4 inches = h
Step-by-step explanation:
A = 1/2bh in terms of h
Multiply each side by 2
2A = bh
Divide by b
2A/b = h
Let A = 18 and b = 9
2*18/9 = h

Answer:
x = 960
Step-by-step explanation:
Using the Altitude- on- Hypotenuse theorem
( leg of large triangle )² = ( part of hypotenuse below it) × ( whole hypotenuse), so
x² = 576 × (576 + 1024) = 576 × 1600 = 921600 ( take square root of both sides )
x = [tex]\sqrt{921600}[/tex] = 960

3x - 4y + 5 = 0
Step-by-step explanation:
The equation of a line in general form is
Ax + By + C = 0 ( A, B, and C are integers )
Given
y + 1 = [tex]\frac{3}{4}[/tex] (x + 3) ← multiply through by 4 to clear the fraction
4y + 4 = 3(x + 3)
4y + 4 = 3x + 9 ( subtract 4y + 4 from both sides )
0 = 3x - 4y + 5 , that is
3x - 4y + 5 = 0 ← in general form

list 2 differences between y = sin x and y = cos x
Answers
Answer:
- sin(x) is the ratio of the opposite leg to the hypotenuse in a right triangle, while cos(x) is the ratio of the adjacent leg to the hypotenuse in a right triangle.
-The graph of y = sin(x) at x = 0 starts at the origin, and then increases, while the graph of y = cos(x) starts at a max, and then decreases.
Here's a 3rd: sin(x) is the cofunction of cos(x), which means that sin(x) = cos(90-x). This also shows that they are different.
