Step-by-step explanation:
I believe you wanted to type that the volume of a cylinder is 40 cubic feet, and try to find what the volume of the same base and height would be in comparison.
Recall that the volume of a cylinder of base B and height H is given by the formula:

Recall as well that the volume of a cone of base B and height H is given by the formula: 
Therefore, if the cone has the same base (B) as the cylinder, and equal height (H), then we can say that the volume of the cone is "one third" of the volume of the cylinder, which in Math terms is written as:

Therefore, in our case, given that the volume of the cylinder is 40
, the volume of the cone would be:

Answer:
30, 150, and 150
Step-by-step explanation:
If you have two intersecting lines, there are going to be four angles that will all sum 360 degrees. The opposite angles will be identical. So, if you have one of the angles and it is 30 degrees, the opposite angle will be of 30 degrees as well. That adds 60 degrees, meaning that the remaining two angles will sum 300 degrees, and as they will also be identical, each will be of 150 degrees.
