Answer:
3pi
Step-by-step explanation:
First find the area of the entire circle
A = pi r^2
A = pi * 2^2
A = 4 pi
We know that this is 3/4 of a circle so multiply the area by the fraction of the circle
3/4 * 4 pi
3 pi
All we have to do is divide how many blueberries he ate in an hour (80) by how many times 15 minutes is in 1 hour (4)
80 ÷ 4 = 20
We can check our work by multiplying 20 by 4
20 x 4 = 80
Therefore, David ate 20 blueberries in 15 minutes
Hope this helps you!

Answer:
x = 45 and y = 90
Step-by-step explanation:
Let the third angle be z
z = 180 - 135 (Linear Pair)
z = 45
Since its an iscosceles triangle,
<z = <x (angles opposite to equal sides have equal angles)
<x = 45 degree
<z + <x + <y = 180
45 + 45+ <y = 180
90 + <y = 180
<y = 180 - 90
<y = 90
Therefore x = 45 and y = 90
