30 POINTS NEED HELP ASP

X= 20

Step-by-step explanation:

If x = 20 than going from up  to down when looking at this angle...

20+

2(20) +

(20 + 10) +

=

20

40

30+

=90

When the angle has a square right where it bends then all of the numbers combined (added) must equal a total of 90

another simple way to solve this could take a little longer but would be

90= x + 2x + (x + 10)

90= 3x + (x + 10)

90 =4x + 10

-10         -10

80 = 4x          <  Divide both sides by 4

 4      4

 20 = x   or x =20

Hope this helped and was wondering if you could mark me as the brainliest
