Question

the angles of an triangle are in ratio of 3:2:7. find each angle

Answer 1

Answer:

let all the three angles be x .

i.e., 3x , 2x and 7x .

sum of angles of triangle = 180°

3x + 2x + 7x = 180°

12x = 180°

x = 15°

thus, 3x = 3*15° = 45°

2x = 2*15° = 30°

7x = 7*15° = 105°

Answer 2

Answer:

measure of 1st angle =45

measure of 2nd angle =30°

measure of 3rd angle = 105°

Step-by-step explanation:

let take common multiple be x.

so,measure of

1st angle = 3x

2nd angle =2x

3rd angle = 7x

sum of all angles of triangle =180°

3x + 2x + 7x =180°

12x =180°

x =180°/12

x= 15

so , measure of

1st angle = 3x =3×15=45°

2nd angle = 2x = 2×15 = 30°

3rd angle = 7x = 7×15= 105°
