Question

what is the measure of the complement of the angle 80°?
​

Answer 1

Answer:

75° is the complement of the angle 80°

Answer 2

Answer:

Measure of the angle complement to 80° is 10°.

Given:

Measure of an angle is 80°.

To find:

Measure of an angle which is complement to 80°.

Solution:

Let the measure of the other angle be x.

We know that, measure of two complementary angles = 90°.

So, x+80° = 90°

=> x = 90°-80°

=> x = 10°.

Therefore, measure of the angle which is complement to 80° is 10°.

Verification:

Sum of complementary angles = 90°

=> 80°+10° = 90°

=> 90° = 90°.

Something more related to it:

Sum of complementary angles = 90°.

Sum of supplementary angles = 180°.

Sum of all the angles of a rectangle = 360°.

Sum of all the angles of a square = 360°.

Sum of all the angles of a parallelogram = 360°.

Sum of all the angles of a triangle = 180°.
