Question

21 and 22 are complementary angles. The measure of Z1 is 52º. The measure of Z2 is 2x°. Find the value of x. The figure is not drawn to scale. ​

Answer 1

x = 19

Explanation:

Complementary angles sum to 90°

given ∠ 1 = 52° , then

∠ 2 = 90° - 52° = 38°

given ∠ 2 = 2x , then

2x = 38 ( divide both sides by 2 )

x = 19
