Answer:

x = 15

Step-by-step explanation:

Angle Formed by Two Secants = 1/2(DIFFERENCE of Intercepted Arcs)

2x +15 = 1/2 (10x+20 - 80)

Multiply by 2

4x+30 = (10x+20 - 80)

Combine like terms

4x+30 = 10x-60

Subtract 4x from each side

30 = 6x-60

Add 60 to each side

90 =6x

Divide by 6

15 =x
