Question

If the complement of an angle is 79°, then the angle will be of ______.

Options

• 1°

• 11°

• 79°

• 101°

Answer 1

If the complement of an angle is 79°, then the angle will be of 11°.

Explanation:

When the sum of the measures of two angles is 90°, the angles are called complementary angles. Each of them is called a complement of the other.

The given complement of an angle is 79°

Let the measure of the angle be x°.

Then,

x + 79° = 90°

x = 90° – 79°

x = 11°

Hence, the measure of the angle is 11°.
