Use trigonometry to solve for x.
The tangent function is defined to be opposite side divided by the adjacent side.
tan(78) = x/10
tan(78)(10) = x
47.0463010948 = x
We now round off to two decimal places. In other words, we round off to the nearest tenths.
47.05 = x
Done!
B is your answer if you need me to explain why just ask me :) have a good day
To get the volume of the pile it is 4 x 4 x 16 so if each cord is =to 1 then the answer is 256
