Answer:

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

$(2x-2)\°=(2(47)-2)=92\°$
