Parallel lines "a" and "b" are cut by a transversal "c." What is "R" in the diagram below?

Answer:
I'm guessing it's 70°
Step-by-step explanation:
in the image above you can see I circled the 70°
the same angle is below it to the left. which means it's 70°
Either C) 70 or B) 110
because its not a right angle
we would know. and it isn't small enough to be 20 degrees
so u take from there and decide
