Part a: what is the measure of angle x? show your work. part b: explain how you found the measure of angle x by identifying the angle relationships that you used along the transversal.

The missing part of ∠R = 70°. Hence, you can find the missing ∠R in the triangle (70°). 180°-110°=70°

Next x+64=110. The reason why you can do this is because ∠R is going to be an opposite interior angle. Subtract 64 from the left and right sides. x=46

I hope this helps!
