Step-by-step explanation:

There are 721 freshman.
Make 35% a decimal, multiply by 2060
.35*2060=721
4 more toy boats are in each group than toy cars
To answer this problem, you should know the formula that we will be using and this would be:
Angle of elevation = arc tan( (vertical height)/(length of the shadow)).
Plugging in the values in the formula. Here, this angle is:
arc tan (12.5/18) = <span>34.78 degrees</span>
The answer would be approximately 34.78 degrees
