All you have to do is draw two circles then make lines in the circles so that you have 8 pieces, do that twice.
Answer:
The possible values of x are 90°, 30° and 150°.
Step-by-step explanation:
Given that,
sin(2x) = cos(x) where 0° ≤ x < 180°
We know that, sin(2x) = 2 sinx cosx
2 sinx cosx = cosx
Subtract cosx on both sides
2 sinx cosx - cosx = 0
cosx (2sinx-1)=0
It means, cosx = 0 and (2sin x -1 ) = 0
cos x = cos0 and sinx = 1/2
x = 90° and x = 30°, 150°
Hence, the possible values of x are 90°, 30° and 150°.

Answer:
Volume of the cone= 
Step-by-step explanation:
Volume of a right circular cone:
For, height(h)= 4.5 feet
Diameter= 19 feet
Radius(r)= 19/2= 9.5 feet
As, 
Volume of the cone :
The volume of the cone with given dimensions is
