Triangles ABC and DEF are similar. If ∠ABC = 121°and ∠BCA = 35°, find the measure of angle FDE.

Answer 1

angle A = 180-121-35 = 24°
since angle FDE corresponds with angle CAB
angle D = 35°

Answer 2

Hmm. Looks to me like ∠D corresponds to ∠A = 24°

Answer 3

Steve is right, pardon the senior moment, and my diagram even has D corresponding with A

Answer 4

180-121-35=24 degrees
