Question

Find m angle1 and m angle 2. Justify your answer. m angle 1= 50° by the corresponding angles postulate. m angle 2= ° ..... by the A) alternate exterior angles theoremB) same-sided interior angles theoremC) vertical angles theoremD) alternate interior angles theoremE) corresponding angles postulate

Answer 1

for this case the best answer for the first part would be:

B) same-sided interior angles theorem

And by this theorem the sum of these angles needs to be:

m < 1 + m< 2= 180

and solving for m < 2 we got:

m< 2 = 180 - 50 = 130º
