Question

I need help solving this math problem any help ?

Answer 1

We know that m and n are parallel.

Then, x is supplementary of 145 degrees.

This is because the adyacent (and supplementary) angle of x is, with the angle of measure 145 deg, alternate exterior angles and have the same measure.

Therefore, x and the angle of 145 degrees are also supplementary.

If they are supplementary, they add 180 degrees, so we can write:

`\begin{gathered} x+145=180 \\ x=180-145 \\ x=35 \end{gathered}`

x = 35 degrees
