Correct Answer - Option 3 : 70°
Given
If Δ ABC is similar to Δ DEF, such that ∠ A = 47° and ∠ E = 63°
Concept used
Similarity of triangle
Calculation
Δ ABC ∼ Δ DEF
∠ A = ∠ D, ∠ B = ∠ E, ∠ C = ∠ F
∠ A = 47° and ∠ B = 63°
In Δ ABC sum of all angles equals to 180°
∠ C = 180° - (47 + 63)
∠ C = 180° - 110°
∠ C = 70°
