Question

The angles of a triangle are in the ratio 3 : 7 : 8 .Find the measure of all the three

angles.​

Answer 1

Answer:

3x+7x+8x= 180

18x = 180

x= 10

Hence, measure of all 3 angles is:

3x=30

3x=307x=70

3x=307x=708x=80

Hope you find it helpful.

Answer 2

Answer:

30°,70°,80°

Explanation:

sum of angle of triangle =180°

ratio =3:7:8 = 3+7+8

=18

angle of triangle = 180° /18

=10°

1st angle = 3×10°

=30°

2nd angle =7×10°

=70°

3rd angle =8×10°

=80°
