Help Asap !Solve For X In The Diagram.

x = 6.111

Step-by-step explanation:

The supplement of <AST = 180 - (23x - 5) That supplement is inside the triangle.

Solution

Add the three angles together to get 180

180-(23x - 5) + 14x-5 + 55 = 180         Remove the brackets

180 - 23x + 5 + 14x - 5 + 55 = 180      Combine

-9x + 55 + 180 = 180                        Subtract 180 from both sides.

-9x + 55 = 0                                     Subtract 55 from both sides

-9x = - 55                                         Divide by -9

x = -55/-9

x = 6.111

Check

180 - (23*6.111 - 5) + 14*6.111 - 5 + 55= 180

180 - 140.555 + 5 + 85.555 -5  + 55 = 180

39.445 + 85.555 + 55 = 180

180 = 180
