Simplify please need help

Hey there!

This simplifies to:

And when multiplied we get: 7/4

Let me know if this helps :)

1) <2 and <4 are vert. angles=given

2)lines m and n intersect at P=def. of vertical angles

3)<2 and <3 are a linear pair=def. of a linear pair

4)m<2 + m<3=180 = angles addition postulate

5)<3 and <4 are a linear pair =def. of a linear pair

6)m<3 + m<4=180 = angle addition postulate

7)m<2+m<3=m<3+m<4 = substitution property

8)m<2=m<4 = subtraction property

9)<2=<4 = definition of = angles
