Answer:
<1 = 112degrees
<2 = 33degrees
Step-by-step explanation:
From the figure, the sum of interior angles of the larger triangle is equal to the exterior, hence;
<1 + 15 = 127
<1 = 127 - 15
<1 = 112degrees
For the smaller triangle;
<1 = <2 + 79
112 = <2 + 79
<2 = 112-79
<2 = 33
Hence the measure of <2 is 33degrees

Answer:
height (h) = 6.0 inches ( to nearest tenth)
The formula for calculating volume (V) of a cylinder is
V = πr²h → ( r is radius and h is height)
given V = 384π then
πr²h = 384π
divide both sides by π
r²h = 384
8²h = 384
64h = 384
divide both sides by 64
h = = 6
