Answer:

x = 20

Step-by-step explanation:

By exterior angle theorem, we have:

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

Step-by-step explanation:

equation to use: y1-y2/x2-x1 so you get -3/-4 so your slope is 3/4 and you plug that into one of your point equations im going to use the first one so 2=3/4(1) +b so you are going to get 5/4 for b so your equation is y=3/4x + 5/4
