A. Vertical angles.

Complementary angles are adjacent angles that add to equal 90 degrees.
Adjacent angles are angles that share a side (they are right next to each other).
Supplementary angles are adjacent angles that add to equal 180 degrees.

Thus the answer is A.

Hope this helps.

Answer:

we have:

$v = \frac{1}{3} \pi \: r {}^{2}h \\ \\ = > 60\pi = \frac{1}{3} \pi \: r {}^{2} h \\ \\ < = > 180 = r {}^{2} h$

=> r²h = 10.18 = 9.20 = 5.36 = 6.30 = 4.45 = 12.15

=> only r²h = 5.36 satisfy the problem

=> h = 5

h = 5 r = 6

h = 5 r = 6=> d = 12
