Answer:
(x, y) = (-2, -4)
Step-by-step explanation:
A graphing calculator can provide excellent help with graphing. Apps and websites are available, if your calculator doesn't do that.
The two lines intersect at the solution point: (x, y) = (-2, -4).
The volume of a rectangular prism is the product of the three dimensions.
The width and length give the base area, which is 90.
So, if we multiply the base area and the height, we get the volume:

We know that V=1080 and w*l (i.e. the base area) is 90. So, we have

Complementary angles sum to 90°
the complement of 64° = 90° - 64° = 26°
