Step-by-step explanation:

10.) 5x - 14 + 3x + 90 = 180 (collect like terms)

8x + 76 = 180 (subtract 76 on both sides)

8x = 104

x = 13

11.) 51 + 83 + 7b - 10 = 180 (collect like terms)

124 + 7b = 180 (subtract 124 on both sides)

7b = 56 (divide by 7 on both sides)

b = 8

6a - 3 = 51 (add 3 on both sides)

6a = 54 (divide by 6 on both sides)

a = 9

12.) <U is 54 since this is an isosceles triangle.

c. is the only one that shows that.
