Answer: 6.25
create a ratio of 2.5/2 = x/5 and solve for x. First multiple both sides by 10 so you get 12.5 = 2x. Then you get x = 6.25.
The y intercept of this question is 0
X=3
okay so Angles YXZ and YZX are congruent.
180 = 136 + 2(10x-8).
180-136 = 2(10x-8).
44 = 2(10x-8).
44/2 = 10x-8.
22=10x-8.
22+8 = 10x.
30 = 10x.
3 = x.
