Question

Use the diagram to find the measure of the given angle.

Select one:

a. 110

b. 120

c. 130

d. 140

mDAF

Answer 1

Answer:

  c. 130

Step-by-step explanation:

∠FAB is a vertical angle with the one that is marked, so is 50°. ∠FAE is the complement of that, so is 40°. ∠DAF is the sum of the right angle DAE and angle FAE, so is ...

  90° + 40° = 130° = m∠DAF
