Answer:
720º
Step-by-step explanation:
We can use vertical angles to figure this out. We can see that each of the unmarked angles in the triangles is a vertical angle to an empty space. A full circle has the measure of 360º. We need half of that which is 180º.
The sum of the angle measures of a triangle is 180º. We have five triangles so the total angle meaure is 900º.
However, we need to subtract the 180º to get 720º.
The length of river c is 2910 miles and the length of river d is 2610 miles.
Just subtract 300 from 5520 and divide by 2 and that's the length of river d and then add 300 to that and you will get the length of river c...
Answer:
176.7 square feet
Step-by-step explanation:
Diameter, d = 15 feet
radius, r = d/2
r = 15/2 = 7.5 feet
π = 3.142
Area of the pool = area of a circle
= πr^2
= 3.142 * 7.5^2
= 176.7375
to the nearest tenth
= 176.7 square feet
