Two angles are complementary if the sum of their measures is 90 degrees . If the measure of an angle is 7 x ​degrees, represent the measure of its complement as an algebraic expression in x.

Respuesta :

Answer:

90 - 7x

Step-by-step explanation:

We have that ∠ 1 + ∠ 2 = 90 ← ∠ 1 = 7x, thus

7x + ∠ 2 = 90 ( subtract 7x from both sides )

∠ 2 = 90 - 7x

Thus the complement of 7x is 90 - 7x
