Question

What is b? I need help answering this question.

Answer 1

Hi! 

The line that the 36 degree angle rests on is a straight angle, meaning that it measures 180 degrees. This straight angle is split up into two separate angles. Since we already know one of the angle measures we can do some simple subtraction to get the angle measurement for angle b. 

180-36=144

So angle b measures 144 degrees. 

Hope this helps :)
