kiruha [24]

Answer:

70

Step-by-step explanation:

By exterior angle theorem:

(2x + 12) \degree = 112 \degree + 180 \degree - 2x \degree \\  \\ (2x + 12) \degree = 292 \degree - 2x \degree \\  \\ (2x + 12) \degree  + 2x \degree = 292 \degree \\  \\ (2x + 12 + 2x) \degree = 292 \degree \\  \\ (4x + 12) \degree = 292 \degree \\  \\ 4x + 12  = 292  \\  \\ 4x = 292 - 12 \\  \\ 4x = 280 \\  \\ x =  \frac{280}{4}  \\  \\ x = 70
