Question

What are the measures of the two angles in the figure below?

A. 46 and 44

B. 67 and 23

C. 52 and 38

D. 25 and 75

Answer 1

Both angles form a complementary angle, which means that their sum is equal 90 degree.

5x+7 +3x+11=90 Combine like terms

8x+18=90 Subtract 18 in both sides

8x =72 Divide by 8 in both sides to isolate x

x=9


As you have the value of x, you can find the value of each expression


5(9)+7= 52 3(9)+11=38


The correct answer is letter C, 52 and 38.
