Answer 1

✿ Correct Questions

In Δ ABC ∠A = 3B , ∠B=B, ∠C = 2B. Find the angles of Δ ABC.

✿ Solution

✿ Given

∠A = 3B

∠B= B

∠C = 2B

• We know that sum of all angles of triangle is 180°.

IN Δ ABC

∠A + ∠B + ∠C = 180°

↬ 3B + B + 2B = 180

↬ 6B = 180

↬ B = 180 / 6 = 30°

↬ B = 30°

Now

• ∠A = 3B = 90°
• ∠B= B = 30°
• ∠C = 2B = 60°
