Answer:
85 degrees.
Those two quads are Similar polygons. Just match up the shape and basically do 360 - 110 - 75 - 90 = 85.
Q1

16
π
Explanation:
To find the circumference of a circle, you need the radius.
Remember that the area of a circle is
A
=
π
r
2
Since we know the area, we can plug it in for
A
64
π
=
π
r
2
64
π
=
π
r
2
64
=
r
2
Take the square root of both sides to find the radius:
r
=
8
Now, use the circumference formula of
2
π
r
C
=
2
π
(
8
)
This simplifies to the circumference equalling
16
π
Answer:
Short Answer is C.
Step-by-step explanation:
182 students out of 400 live off-campus, so 182 divided by 400 = .455 or 45.5%
The above fraction can be written as :
So, the Simplest form of given expression is 33/2
