• 107°

• 73°

Find the indicated angle measure. (What is ?)

• 51°

• 37°

• 167°

Set up an equation to find x.

• 42 + 8x = 2 + 12x

• 2 + 12x + 42 = 8x

• 42 + 8x + 2 + 12x = 180

• 42 + 8x = 180

Set up an equation to find x.

• 52 + 5x + 16 + 10x + 8 = 180

• 52 - 5x + 16

• 52 + 5x + 16 = 10x + 8

• 52 + 10x + 8 = 5x +16
