Question

Triangle ABC and DEF are congruent. Find x.

Answer 1

Δ ABC ≡ Δ DEF

⇒ ∠DFE = ∠ACB = 50°

.

Solve x:

x - 8 = 50

x = 58°

.

Answer: x = 58°

Answer 2

Answer with explanation:

It is given that

⇒ Δ ABC ≅ Δ DEF

The sides of  triangles are written in Clockwise direction.

∠A= ∠D

∠B=∠F

∠C=∠E

→ ∠B=∠F  

→65°= (x-8)°

→x=65°+8°

→x=73°
