Take a look at the attachment below. It fills in for the attachment that wasn't provided in the question -
An oblique pyramid is one that has a top not aligned with the base. Due to this, the height of the pyramid connects with two vertices at its ends to form a right angle present outside the pyramid, knowing that it is always perpendicular to the base. There is no difference between the calculations of the volume of an oblique pyramid and a pyramid however -

<u><em>And thus, you're solution is 5 cm^3, or in other words option b!</em></u>
8/x + 2 is equal to 8/4 + 2.
8/4 = 2
2 + 2 = 4
ANSWER: 4
Interest earned = rate charged × amount invested
Interest = 3/100 × $3000 = $90
Account balance after one year = Amount invested + Interest earned
Account balance after one year = $3000 + $90 = $3090
Check the picture below.
notice the bottom part of the picture, just using the tangent of the angle, we can get the angle itself, and you'd know what "x" and "y" are from the above part.
how much farther would they have to walk up? well, the hypotenuse of the longer triangle is "h", the hypotenuse of the shorter triangle is 122, so, they'd have to walk " h - 122 " more.
When trying to determine the distance between two points, one would use the distance formula.
The distance formula is attached above and all you need to do is plug in the points in order to get the distance.
For example, if you were to plug them in, you would get:
√(0+4)^2 + (0+2)^2
