Question

What is the value of b?

Answer 1

b=105°

what I do is I just add the two degrees you already have and since we know the long line is 180° you would just subtract 180 and 75 :•)

Answer 2

105°

Explanation:

since its a straight line then put it equal to 180. First we add and then subtract from 180, like this.

52+23=75

180-75=105
