Answer:

x = 14

Step-by-step explanation:

4x° + (3x + 20)° + (3x + 20)° = 180° (sum of interior angles; isocleces triangle)

10x + 40 = 180

10x = 140

x = 14

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
