Question

21 and 22 are complementary angles. The measure of Z1 is 60°. The

measure of 22 is 5(x - 1)º. Find the value of x.

Answer 1

The value of x is 7

Explanation:

Complementary angles have a sum of 90°, therefore the equation to solve for x is:

∠1+∠2=90°

60°+5(x-1)°=90°

5(x-1)=30°

x-1=6

x=7

So the value of x is 7
