The angles of a triangle are in the ratio 2:3 : 4. The largest angle of thetriangle is(a) 120°(b) 100°(c) 80°(d) 60° |
|
Answer» Answer: AnswEr : The LARGEST angle of the triangle is 80° (option C) . ⠀━━━━━━━━━━━━━ GiveN : Angles of the triangle are in the ratio 2 : 3 : 4 To FinD : Largest angle of the triangle = ? SoluTion : Let's ASSUME the VALUES of angles as, ∠A = 2x ∠B = 3x ∠C = 4X ⠀━━━━━━━━━━━━━ Now, We know that the sum of all the angles of a triangle is 180°(Angle sum property). So, in any ΔABC ∠A + ∠B + ∠C = 180° Substituting the values as PER our assumption, ➠ 2x + 3x + 4x = 180° ➠ 9x = 180° ➠ x = 180°/9 ➠ x = 20° ⠀━━━━━━━━━━━━━ ★ So, the angles are : ∠A = 2x = 2(20) = 40° ∠B = 3x = 3(20) = 60° ∠C = 4x = 4(20) = 80° ∴ The largest angle is 80° Hope it helps. |
