Question

if ∆abc~∆def such that angle a=45° and angle E= 56°, then find angle C.

Answer 1

I guess the answer should be 101° For angle C....as in 2 similar triangles the corresponding angles can be equal...
so...angleA=angle D=45°
AngleB=angleE=57°

Answer 2

Angle c is 79.

45+56+c = 180

101+c=180

C=180-101

C=79
