The smaller angle is 60 degrees and the larger angle is 120 degrees.
x+2x = 180, 3x=180, so x = 60 and 2x = 120.
Answer: 
Step-by-step explanation:
V=hpir²
h=8
d=2r
d/2=r
5/2=2.5=r
V=8pi2.5²
V=8pi6.25
V=50pi
aprox pi=3.14
V=50 times 3.14
V=157 in³
157 cubic inches
This strategy works because if you subtract one number from another the sum of the two numbers should be the that is being subtracted from. (In this case, it's 200)
