Question

triangle abc is similar of triangle def ,if angle a =45°and angle e=35° then angle b=?​

Answer 1

Answer:

Correct option is

D

79

∘

ΔABC∼ΔDEF ...Given

⇒∠A=∠D ...C.A.S.T.

⇒∠B=∠E ...C.A.S.T.

⇒∠C=∠F ...C.A.S.T.

∴∠B=∠E=56

o

In ΔABC,

∠A+∠B+∠C=180

o

....Angle sum property of triangles

⇒45

o

+56

o

+∠C=180

o

⇒∠C=79
