Answer:
x = 111 degrees
Step-by-step explanation:
the angle next to 164 degrees :
any line = 180 degrees, so 180 - 164 = 16 degrees
now you have two out of three angles in the triangle. All three angles of every triangle must add together to equal 180, so
180 = 53 + 16 + x
or
x= 180 - 53 - 16
x=111 degrees

200
Step-by-step explanation:
5*360/9=200
Volume of a cone=(1/3)πr²h
Data:
π=3.14
radius=diameter / 2=8 in /2=4 in
heitht=8 in.
Volume of this cone=(1/3) *3.14 * (4 in)² * 8 in=133.97 in³,
answer: 133.97 in³
