Answer:
first option
Step-by-step explanation:
Since the triangles are congruent, then corresponding sides and angles are congruent, that is
EF = BC = 10
∠ D = ∠ A = 37°
Answer:
C = 135 Degrees
Why?
Great question. When it says that C and D are supplementary, that means they add up to a specific number in degrees. Supplementary indicates that the angle(s) add up to <u>180 degrees</u>. In this case, since you already know D, and you know it HAS to equal 180, you would do 180 minus 45, which equals 135.
