Question

The complement of an angle is 25°. What is the measure of the angle?

155°


65°


75°


165°

Answer 1

Option 2 - The measure of the angle is 65°.

Explanation:

Given : The complement of an angle is 25°.

To find : What is the measure of the angle?

Solution :

We know that,

Complements are two angles that add up to 90 degrees.

We have given one complement angle i.e. 25°

Let the other complement angle be x.

Then according to definition,

Sum of the angles is 90 degree.

`x+25=90`

`x=90-25`

`x=65`

Therefore, The measure of the angle is 65°.

So, Option 2 is correct.
