Answer:
x
Step-by-step explanation:
factor out both equations and then cancel any of the common factors. You should be left with 4x/4, which simplified is x
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>
Look at the image below :)
In case you didn't know, corresponding angles are equal to each other and are on the same side of the traversal
Therefore the answer is angle CGH
Hope this helped!
