Answer:
35 degrees
Step-by-step explanation:
since both sides are equal, so are the angles involved.
If the diameter is 8 centimeters, the radius is 4. We can use the formula
and plug in r=4 and h=13 to get
, so
.
The perimeter equation for a rectangle is two times the base plus two times the height.
2B + 2H=P
Plug in the known values and solve for x.
2(2x) + 2(x+1)=53
4x+2x+2=53
6x=51
x=8.5
Now that we know what x is, put it back into the formula for the height of the rectangle to find the final answer.
H= x+1
H=8.5+1
H=9.5 ft
1. 3x-6+2x+108+88=360
5x=170
x=34
2. figure B
