Question

In this figure, the two angles are complementary.

(2x + 6)°
(1/2x )°
What is the value of x?

Answer 1

Explanation:

Complementary means angles that add up to 90°

Based on that you can write and equation by adding the 2 angles and making equal to 90

2x+6+1/2x=90 combine like terms on left

5/2x+6=90 subtract both sides by 6

5/2x=84 multiply by the reciprocal of 5/2 => 2/5

x=168/5 or 33.6
