Question

Please help you don’t even have to solve it, I just need the equation

Answer 1

Explanation:

Since the 2 side lines are parallel,

`2x + 40 + 5x = 180 \\ 7x + 40 = 180`

(Note that you can further simplify the equation if you wish to, this is a general equation.)

(Equation formed due to Corresponding angles and Sum of angles on the same straight line)
