Use the diagram to find the measure of the given angle.
Select one:
a. 110
b. 120
c. 130
d. 140
mDAF

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
