Answer:
128 m^3
Step-by-step explanation:
The volume of the rectangular prism base is (8 m)(8 m)(10 m), or 640 m^3.
The triangular 'cap' has a base area of 64 m^2 and a height of 6 m, and thus a volume of (1/3)(64 m^2)(6 m) = 128 m^3
First part 3x+(-5)=19 you need to remove parenthesis move the constant -5 to the right to have 3x=19+5 then add those to get 3x=24 then divide to get x=8
AB and CD are interesting lines
Therefore, the angles formed will be equal (vertically opposite angles).
Hence,
Now,
31
Step-by-step explanation:
We need to find the value of angle D so that we can solve for X. To do that we need to find the value of angle A and that value will be the same value as D because these angles are the same.
To do that we have to add angles C and B together and that equals 118°. Then we have to realize that all the angles of a triangle add up to 180°. So then we have to subtract 118° from 180° and that equals 62°. So now we have the value of A.
If the value of angle A is 62° then that must be the value of angle D because these two angles are the same. So now that we have the value of angle D we need to solve for X. This equation is asking what times 2 equals the value of X. We know the value of X is 62°. So what times 2 equals 62°?
31×2=62°
Therefore the value of X is 31
