WebMar 30, 2024 · Find the three angles. Let ∠A = x & ∠B = y Given that ∠C = 3 ∠B ∠ C = 3y Also, ∠ C = 2 (∠A + ∠B) ∠C = 2 (x + y) For ∠C = 3y Put ∠A = x ∠B = y and ∠C = 3y Since ABC is a … WebSolution Given that, ∠C = 3∠B = 2 (∠A + ∠B) 3∠B = 2 (∠A + ∠B) 3∠B = 2∠A + 2∠B ∠B = 2∠A 2 ∠A − ∠B = 0 … ( i) We know that the sum of the measures of all angles of a triangle is 180°. Therefore, ∠A + ∠B + ∠C = 180° ∠A + ∠B + 3 ∠B = 180° ∠A + 4 ∠B = 180° … ( ii) Multiplying equation ( i) by 4, we obtain 8 ∠A − 4 ∠B = 0 … ( iii)
In a ABC, ∠C = 3∠B = 2(∠A + ∠B) . Find the three angles - Cuemath
