Question

three angles are in the ratio 6:7:5 find all angles it problem of class 7​

Answer 1

Answer:

Sum of all the angles in a triangle is 180.

6x+7x+5x = 180

18x = 180

x = 180/18

x = 10

Substituting the value of x in the angles,

6x = 6x10 = 60°

7x = 7x10 = 70°

5x = 5x10 = 50°

Answer 2

1st angle:- 60°

2nd angle:-70°

3rd angle:-50°

Step-by-step explanation:

Let the angles be X,

i.e 6x,7x and 5x

therefore,

6x+7x+5x=180° (sum of angles of triangle)

18x=180°

x=180°/18

x=10°

So now,

6x=6*10=60°

7x=7*10=70°

5x=5*10=50°..

hence, solved..
