Question

The image below shows two parallel lines cut by a transversal. Using the figure below, solve for x.

Answer 1

the 2 given angles are supplementary...

there is an angle vertically opposite 4x + 20 that is also 4x + 20...
(vertically opposite angles are equal)

then you have 2 co-interior angles... these are angles that are supplementary or add to 180...
so you have

4x + 20 +5x - 50 = 180

now just solve for x

Answer 2

so the answer is 23.3?

Answer 3

@campbell_st

Answer 4

well whatever 210/9 is

70/3 so you answer seems sensible

Answer 5

ok thanks
