Question

In Exercises 15-18, find the measure of the exterior angle.​

Answer 1

The measure of the exterior angle is 92 degrees

Explanation:

Problem 16)

we know that

An exterior angle of a triangle is equal to the sum of the opposite interior angles

so

In this problem

`(2x-2)\°=x\°+45\°`

solve for x

`2x-x=45+2`

`x=47\°`

Find the measure of the exterior angle

`(2x-2)\°=(2(47)-2)=92\°`
