Answer 1

Answer:

[tex]50^{\circ}[/tex]

Step-by-step explanation:

Complementary angles mean that the sum of the angles add up to [tex]90^{\circ}[/tex]. We can use algebra to solve for [tex]x[/tex] and then to determine [tex]m\angle QRS[/tex].

[tex]m\angle QRS + m\angle SRT = 90[/tex]

[tex]8x+10 + 8x = 90[/tex]

[tex]16x = 80[/tex]

[tex]x = 5[/tex]

[tex]m\angle QRS = 8x+10[/tex]

[tex]= 8(5)+10[/tex] (substitution)

[tex]=50^{\circ}[/tex]

∴ [tex]m\angle QRS = 50^{\circ}[/tex]

Hope this helps :)

In the diagram below of triangle BCD, E is a midpoint of BC and F is a midpoint of CD. If EF = 44 - 8x, and BD = 44 - 5x, what is the measure of BD?

Answers

Answer:

BD = 24

Step-by-step explanation:

EF = 44 - 8x,

BD = 44 - 5x.

Since EF is a midsegment of ∆BCD, therefore, based on the Midsegment Theorem,

[tex] EF = \frac{1}{2}(BD} [/tex]

[tex] 44 - 8x = \frac{1}{2}(44 - 5x} [/tex]

Multiply both sides by 2

[tex] 2(44 - 8x) = 44 - 5x [/tex]

[tex] 88 - 16x = 44 - 5x [/tex]

Collect like terms

[tex] 88 - 44 = 16x - 5x [/tex]

[tex] 44 = 11x [/tex]

Divide both sides by 11

[tex] 4 = x [/tex]

x = 4

BD = 44 - 5x

Plug in the value of x

BD = 44 - 5(4) = 44 - 20

BD = 24

Solve for X and Solve for Y

Answer:

x is 56 and y is 65

Step-by-step explanation:

EXPLANATION:
Angles inside a triangle add up to 180 degrees, and the angle of a line is 180 degrees. Given we have the angle outside the triangle of 124, do 180-124 to get x, or 56. Now we add 56 and 59, subtract that from 180, and get our y value!

The submarine is currently located at 10,000 feet below sea level but then rises 5,200. Where is the

a. 4800 feet below sea level
b. 5,200 feet below sea level
a. 14800 feet below sea level d. 15200 feet below sea level

Answers

Answer:

A. 4,800 feet below sea level

Step-by-step explanation:

10,000 feet below sea level = -10,000 feet

"rises 5,200 feet" = +5,200 feet

=-10,000 + 5,200 = -4,800 feet

=4,800 feet below sea level.

Ony scored 22 and 25 points in the first two games of a basketball tournament. Tony's goal is to make the All-Tournament Team. So far, in all of the tournaments he's been to, all of the players who made the All-Tournament Team scored an average between 27 and 32 points in the tournaments. Determine the range of points Tony should score in his next game to make the All-Tournament Team.

Answers

Answer:

34 and 49

Step-by-step explanation:

Calculation to Determine the range of points that should be score in his next game

Based on the information given we were told that he scored 22 and 25 points in the first two games which means that his current scores will be : 22 and 25 point

Secondly we were told that Tony All-Tournament Team as well scored an average between 27 and 32 points in the tournaments based on this we are going to calculate Tony's next score in the next game.

Hence,

Let x be Tony's next score in the next game.

Now let calculate the lower required score of 27 points

(x + 22 + 25)/(25-22) = 27

(x + 22 + 25)/3 = 27

(X+47)=3*27

Collect like terms

x = 81 - 47

x= 34

Let calculate the upper required score of 32 points

(x + 22 + 25)/(25-22) = 32

(x + 22 + 25)/3 = 32

(X+47)=3*32

Collect like terms

x = 96 - 47

x= 49

Therefore the range of points that should be score in his next game will be 34 and 49

Find the measure of each numbered angle

Answers

Answer:

m∠1 = 54° m∠2 = 63° m∠3 = 117°

Step-by-step explanation:

We know that 117 + m∠2 = 180°, which when calculated is equal to 63. Now, we know that 63 + 63 + m∠1 = 180°. This comes out to be 54°. Finally, we know that m∠3 has to equal 117° because they are same side interior angles.

The measure of m<1, m<2 and m<3 are 54, 63 and 63 degrees respectively

The sum of angle in a straight line is 180 degrees, hence:

m<2 + 117 = 180

m<2 = 180 - 117

m<2 = 63 degrees

For the diagram, m<2 - m<3 = 63 degrees (alternate angle.)

Also, the sum of interior angle of the triangle is 180 degrees, hence:

m<2 + m<2 + m<1 = 180

63 + 63 + m<1 = 180

126 + m<1 = 180

m<1 = 180 -126

m<1 = 54degrees

Hence the measure of m<1, m<2 and m<3 are 54, 63 and 63 degrees respectively
