Question

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

Answer 1

Answer:

75, 60, 45

Step-by-step explanation:

5x+4x+3x=180

12x=180

x=180/12

x=15

So,

5 X 15= 75

4 X 15= 60

3 X 15= 45

Answer 2

Answer:

A= 75, B= 60 , C= 45

Step-by-step explanation:

In triangle,

angle A : angle B : angle C = 5:4:3

let, A=5x , B=4x , C=3x

by angle sum property of triangles,

A+B+C = 180

5x+4x+3x = 180

12x = 180

so,. x = 15.

so, A = 5x = 5×15 = 75

B = 4x = 4×15 = 60

C = 3x = 3×15 = 45
