Answer:

x = 58

Step-by-step explanation:

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

51 =1/2 (160-x)

Multiply each side by 2

102 = 160-x

Subtract 160 from each side

102-160 = -x

-58 = -x

Multiply by -1

58 =x

Answer:

x = 58

Step-by-step explanation:

51 \degree =  \frac{1}{2} (160 \degree - x \degree) \\  \\ 51 \times 2 \degree =  160 \degree - x \degree \\  \\ 102 \degree =  160 \degree - x \degree \\  \\ x \degree  = 160 \degree  - 102 \degree \\  \\ x \degree = 58 \degree  \\  \\  \huge \red{ \boxed{x = 58}}
