Question

The two angles are 60 degrees and (x-20) degrees and formed complementary angles as shown in the picture below. Solve for x.

Answer 1

The value of x is 50°.

Explanation:

Complementary angles are two angles whose sum is 90°.

One of the complementary angles is, 60°.

And the other is, (x - 20°).

Compute the value of x as follows:

Complementary 1 + Complementary 2 = 90°

60° + (x - 20°) = 90°

(x - 20°) = 30°

x = 50°

Thus, the value of x is 50°.
