Step-by-step explanation:

Given:-

If the angles of a triangle are in the ratio 3:4:5, then find the largest angle.

Solution:-

=> Angles are in the ratio of 3:4:5

=> let the angle be 3x,4x,5x

=> .°. 3x+4x+5x = 180............sum of the angle of triangle are 180°

=>.°. 12x = 180°

=> .°.x= 15

Now, multiple each angle by x value.

∠A =3×x

∠A=3×15

∠A= 45°

∠B=4×x

∠B=4×15

∠B=60°

∠C=5×x

∠C=5×15

∠C= 75°

Hence, the angle are 45°,60°,75°.

So the largest angle is ∠C 75°.

This is your answer.
