Question

25.
In a triangleABC if AB= 3 cm, AC=3 cm and angle A= 50°, then find angleB.​

Answer 1

Answer:

∠B = 65°

Step-by-step explanation:

In ΔABC,

∠A + ∠B + ∠C = 180°

50° + 2∠B = 180°

2∠B = 130°

∴ ∠B = 65°

Answer 2

Step-by-step explanation:

AB=BC

B=C

A+B+C=180⁰

50⁰+B+B=180⁰ (B=C)

2B=130⁰

B=65⁰
