Answer:
HK=66°
Step-by-step explanation:
Based on the diagram, we know the two sides of the arcs are equal. So we set up an equation that solves for x, then plug it back into one of the sides, and double it.
x+20=6x-45
65=5x
x=13
x+20=33
33x2=66
5 2c 4 8 1 0
140 is the answer for y2 because x1 is 80 more than x2 so you would subtract y2 by 80
