Answer:
B) y = 129º
Step-by-step explanation:
since a triangle is 180º in total, the you have to subtract 71 and 58 from 180 which will give you 51º which gives you the amount for x
and the line that the triangle is on is also 180º in total, so you subtract the 51 from 180 to give you a total of 129º which is the amount for y
21+45+70=136
136+(2+x)=180
First subtract 136 from both sides
(2+x)=44=M<ROS
Subtract 2 from both sides
x=42
