Question

The angles of a triangle are in the ratio 3 : 2 : 7. Find each angle

Answer 1

Answer:

45,30,105

Step-by-step explanation:

the sum of angles in triangle =180

3x+2x+7x=180

12x=180

x=180÷12

x=15

3x=45

2x=30

7x=105

Answer 2

Step-by-step explanation:

Let the angles of triangle be 3x+2x+7x

(sum of angles if triangle = 180 degree

3x+2x+7x = 180 degree

12x = 180 degree

x = 180/12

x = 15degree

1st angle = 3x = 3*15 = 45degree

2nd angle = 2x = 2*15 = 30 degree

3rd angle = 7x = 7*15 = 105 degree
