Question

In the figure below, lines r and s are parallel. What is the measure of <3?

Answer 1

angle 3 = 10x

10x = 4x+42

10x-4x=42

6x=42

x=42/6

x=7


angle 3 = 10x=10*7 = 70


So angle 3 is 70 degrees

Answer 2

Angle 1= 162; 180-162=38; the angle of 3 must be 38

Answer 3

how did you get angle 1 to be 162?

Answer 4

I thought that was what was stated

Answer 5

I don't see it anywhere. The only thing that is known is that angle 3 = 10x = 4x+42
