I believe the answer is 56 cubic feet
Answer:
is a one to one function
Step-by-step explanation:
it is a one to one function
Tan x=opposite/adjacent
cot x=adjacent/opposite
so you need to inverse the fraction
tan x=.78 as a fraction is 78/100
-> inversed= 100/78=1.28=cot x
so it is the second option
I believe this should be right
