Question

Find the angle of a triangle which are in ratio4:5:3​

Answer 1

Step-by-step explanation:

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

Sum of all angles in a triangle is 180°

So,

4x + 5x + 3x = 180°

12x = 180°

x = 180° / 12

x = 15°

4x = 4 × 15° = 60°

5x = 5 × 15° = 75°

3x = 3 × 15° = 45°

Answer 2

Step-by-step explanation:

4x+5x+3x=180°

12x=180°

x=180/12

x=15

4x=4x15=60°

5x=5x15=75°

3x=3x15=45°
