Question

in ∆ ABC , angle C = angle A and BC = 4 cm and AC = 5 cm then find length of AB


WITH CORRECT EXPLANATION
OPTIONS ARE
1) 5cm
2) 4cm
3) 3cm
4) 2.5cm​

Answer 1

Step-by-step explanation:

∆ ABC, ∠ C = ∠ A, BC = 4 cm and AC = 5 cm.

In ∆ ABC,

As ∠ C = ∠ A

Therefore, BC=AB

(Given)

(Sides opposite to equal angles.)

⇒BC=AB=4 cm
