Question

the three angles of the triangle are in ratio 3 ratio 4 ratio 5 ratio find the measure of each angles​

Answer 1

Step-by-step explanation:

Let the common multiple be x

Numbers are:3x,4x,5x

ATQ:

3x+4x+5x=180

12x=180

x=15°

Therefore angles are 3*15=45°

4*15=60°

5*15=75°

Answer 2

Answer:

Step-by-step explanation:

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

Therefore,

3x+4x+5x = 180(by angle sum property of triangle)

12x = 180

X = 180/12

Hence, X = 15

Therefore,

3x = 45 degree

4x = 60 degree

5x = 75 degree
