Question

I need to solve for x. The interior angles are 30 and 4x+2. The exterior angle is 8+6x.

Answer 1

x + y + z = 180 (this is the first equation)

w + z = 180 (this is the second equation)

Now, rewrite the second equation as z = 180 - w and substitute that for z in the first equation:

x + y + (180 - w) = 180

x + y - w = 0

x + y = w
