Answer 1

@thomaster

Answer 2

angle 4 and angle 8 are corresponding angles, they are be same.

so,
<4 = <8
3x = x+40
solve for x, first.

then distribute of x into one of the equations of <4 or <8.
now, get out your answer

Answer 3

So 20?

Answer 4

x =20
then subtitute x = 20 into <4 = 3x
so, <4 = 3 * 20 = 60
