Question

A triangle has interior measures of 32° and 90°. What is the measure of the third angle?

Answer 1

58°

Explanation:

Let the measure of third angle be X

The sum of interior angle of triangle = X

Let's create an equation

`x + 32 + 90 = 180`

Add the numbers

`x + 122 = 180`

Move constant to R.H.S and change its sign

`x = 180 - 122`

Subtract the numbers

`x = 58` °

Hope this helps...
