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

Answer»

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°

Step-by-step explanation:
