Complementary angles are 2 angles who add up to 90 degrees. Every one of the angles adds up to 90 degrees, so the assignment is asking you to find the missing number that makes the angles add up to 90.

Example: The first angle on your pager shows 45 and and a question mark. Ask yourself, what number + 45 = 90? The answer is 45. So, take the number of each angle they give you, and subtract it from 90. ( 90 - 45 ) and you have solved what the missing number ( ? ) is. Hope I helped!

Ratio of the number of students on the team to the number of students trying out for boys is given by
$\frac{16}{40} = \frac{2}{5}$

Since both ratios, simplify to $\frac{2}{5}$ , thus the ratios of the number of students on the team to the number of students trying out is the same for both boys and girls.

Answer:C. 3000 ft

Step-by-step explanation:

First, find the radius of the circumference.

By dividing 1000 ft by 2, which is 500, and that is the radius.

Then you multiply the radius by 3, which is 1500.

Finally, you want the circumference, to find the circumference you need to multiply the radius by 2, which is 3000 ft.

That’s it.
