Solution
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°.
