Hello from MrBillDoesMath!
Answer:
35
Discussion:
Parallel lines cut by a transversal has corresponding angles equal. . So the corresponding angles x and (3x-70) are equal. That is,
x = 3x - 70 => add 70 to both sides
x + 70 = 3x => subtract x from both sides
70 = 3x - x = 2x => divide both sides by 2
x = 70/2 = 35
which is the third choice
Thank you,
MrB
