Answer:

See solutions below

Explanation:

2) angle at the vertex is half that of its intercepted arc;

51 = 1/2(14x-38)

51*2 = 14x-38

102 = 14x-38

14x = 102 + 38

14x = 140

x = 140/10

x = 14

3) 9x+7 = 1/2(68)

9x + 7 = 34

9x = 34-7

9x = 27

x = 27/9

x = 3

4) 114 = 1/2(30-(8x-36+40))

114 = 1/2(360-8x+36-40)

114*2 = 356 - 8x

-8x = 228-356

-8x = -128

x = 128/8

x = 16
