The angles of a triangle equal 180 degrees when added together. We will use this logic to solve all three for x. We will use inverse operations and combine like terms to solve.

[30] Answer: x = 36

Step-by-step explanation:

2x + 2x + x = 180

5x = 180

x = 36

[31] Answer: x = 9

Step-by-step explanation:

* the little box represents 90 degrees

7x + 3x + 90 = 180

10x = 90

x = 9

[32] Answer: x = 45

Step-by-step explanation:

2x + x + x = 180

4x = 180

x = 45
