Creating Equations to Solve for Missing Angles

Multiple Choice

Which equation can be used to solve for (x) in the following diagram?

• 3x + (8x -20) = 90

• 3x = 8x - 20

• 3x + 90 = 8x - 20

• 3x + (8x - 20) = 180

Multiple Choice

Which equation can be used to solve for (x) in the following diagram?

• 5x =13x

• 13x - 5x = 180

• 5x + 13x = 180

• 5x + 13x = 90

Multiple Choice

Which equation can be used to solve for (x) in the following diagram?

• 10x + 10 + 110 = 180

• 10x + 10 = 110

• 10x + 10 = 90

• 10x + 10 - 110 = 90
