Question

Solve for x in the diagram below.

Answer 1

Answer:

45

Step-by-step explanation:

2x+45+x=180 simplify to 3x+45=180. Subtract 45 on both sides then divide by 3 to get 45

Answer 2

Answer:

Step-by-step explanation:

2x + 45 + x = 180     {linear pair}

     3x + 45 = 180

              3x = 180 -45

              3x = 135

                x = 135/3

                x = 45
