Question

If three angles of triangle are 3x, 4x and 5X, the value of X is ?​

Answer 1

Step-by-step explanation:

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

12x=180°

x=180°/12

x=15

Answer 2

Answer:

let the angles be 3x,4x,5x

3x+4x+5x=180

12x=180

x=180/12

x=15

3x=15×3=45

4x=15×4=60

5x=15×5=75
