I have included a chart to identify which angles are congruent (only alternate exterior/interior and corresponding). Basically if they are not alternate exterior/interior or corresponding, then they add up to = 180 degrees.

So since these angles are same side interior, they add up to = 180 degrees. We can write this as: A + B = 180

A + B = 180

2x + 76 = 180

2x = 104

x = 52

I hope this helps!

In what different ways can 45 be written as the product of two positive integers?

First you need to know its common factors.

They are: 1, 3, 5, 9, 15, 45

And 45 = 1*45 = 3*15 = 5*9

So there should be 3 ways in total
