Answer:

x=5

Step-by-step explanation:

So this is a vertical angles, which means two angles across from each other on intersecting lines are congruent

Simply multiply 2 to the both given

2(2x)+2(4x+150)=360

It is equal to 360 since the whole angle is 360

4x+8x+300=360

12x+300=360

transpose 300 to the right side

12x=360-300

12x=60

divide both sides by 12

x=5

Therefore the x is 5

Checking:

2(5)

=10

So it's vertical angle the one across 2x is also 10

4(5)+150

=170

So it's vertical angle the one across 4x+150 is also 170

add them all and see if its 360

10+10+170+170=360

360=360
