Question

PICTURE ABOVE ^^
solve for x

PLEASE HELP !!!!!!

Answer 1

x=18

Explanation:

angle 3 + 120 degrees is equal to 180. angle 3 =60

angle 3 (60) is equal to (3x+6)

solve the equation. 60=3x+6

x=18

Answer 2

x=18 or B

Explanation:

number one is equal to 120 degrees so since the number one and 3x+6 are a straight line it equals 180 degrees

So the equation would be 180=120 + (3x+6)

First you would add like terms

180=126+3x

Then you subtract 126 from both sides to get 3x alone

54=3x

next divide both sides by 3 or multiply by 1/3 to find x

x=18
