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
It's a right triangle. Use the pythagorean theorem. 36^2+r^2=(r+12)^2. r=48.
