m∠R = m∠FB.

m∠R = 40°C.

m∠S = 56°D.

Which equation can be used to determine the measure of ∠F ?2.

56 + 40 + x = 90A.

x – 56 – 40 = 180B.

56 + 40 + x = 180C.

Answer: ________°

Angles CFD and DFE are complementary angles. Which expression can be used to determinex?

3.

40 + 2x = 180A.

2x + 40 = 90B.

2x = 40C.

40 – 2x = 90D.

A pair of vertical angles is formed by lines AD and BE. What is the measure of angle AFB?4.

Which equation can be used to determine the value of x using the linear angle pairs formedby angles AFB and AFE?

5.

(x + 15) + 140 = 360A.

140 – (x + 15) = 180B.

140 + (x + 15) = 180C.

140 – (x + 15) = 90D.
