Question

if the angles of a triangle are in the ratio 3:4:5 . find the value of each angle.​

Answer 1

Let the angles be 3x, 4x and 5x

Then,

3x + 4x + 5x = 180 (Angle sum property of a triangle)

12x = 180

x = 15

The angles are

1. 3x = 45

2. 4x = 60

3. 5x = 75

Answer 2

The ratio of angles of triangle is 3:4:5【given】

Let the multiple be x.

3x+4x+5x=180°【Sum of all angles of triangle is 180°】

12x=180°

x=15

angels are

●3x=3×15=45°

●4x=4×15=60°

●5x=5×15=75°
