Answer 1

x 7 x16

is the answer

Explanation:

is the answer

Answer 2

x = 7 and x = 16

Explanation:

the measure of a secant- secant angle is half the difference of the measures of the intercepted arcs.

11

39 =
`(1)/(2)` (17x + 6 - (7x - 2) ) ← multiply both sides by 2 to clear the fraction

78 = 17x + 6 - 7x + 2

78 = 10x + 8 ( subtract 8 from both sides )

70 = 10x ( divide both sides by 10 )

7 = x

12

54 =
`(1)/(2)` (13x - 6 - (5x + 14) ) ← multiply both sides by 2 to clear the fraction

108 = 13x - 6 - 5x - 14

108 = 8x - 20 ( add 20 to both sides )

128 = 8x ( divide both sides by 8 )

16 = x
