The ratios of the angles in abc is 3: 5: 7. find the
measure of the angles

Step-by-step explanation:

If the ratio of triangle = 3:5:7

Total ratio = 3+5+7 = 15

The sum of angle in a triangle is 180°

1st angle= 3/15× 180 = 3 × 12 = 36°

2nd angle= 5/15 × 180 = 5 × 12 = 60°

3rd angle= 7/15 × 180 = 7 × 12 = 84°

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
