Mathematics

SOVA2 [1]3 years ago
5 0

Answer:

x = 20

Step-by-step explanation:

By exterior angle theorem, we have:

(4x + 2) \degree + (2x  - 9) \degree = (5x + 13) \degree \\  \\(4x + 2 + 2x - 9) \degree  = (5x + 13) \degree\\  \\(6x  - 7) \degree  = (5x + 13) \degree \\  \\ 6x - 7 = 5x + 13 \\  \\ 6x - 5x = 13 + 7 \\  \\ x = 20
