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.
