Answer 1

72 degrees.

Explanation:

The first step would be finding E. We know that a straight line would be 180 degrees. Therefore, we would subtract 180-130=50.

100+102+50+b=360

252+b=360

-252 -252

b=108

Then we would subtract 180-108=72.

Therefore, because it is the angle we are looking for.

Your answer would be the measure of angle ABC is 72 degrees.

Answer 2

The answer is 72

First you find E=180-130=50

Then you add all the angles and subtract from 360

102+100+50=252

360-252=108

then you do 180-108=72
