Let the first angle be A and the second be B.
Complementary angles add up to 90° so:
A + B = 90
We are also told:
A = 6 + 3B; substituting this into the first equation:
6 + 3B + B = 90
B = 21°
A = 6 + 3(21)
A = 69°

ik i didnt spell right
Step-by-step explanation:
Surface area of bin:
A = 2(pi)rh + 2(pi)r^2
Assuming you use 3.14 for pi:
A = 2(3.14)(9)(30) + 2(3.14)(81)
A = 2204.28ft^2
