X = 37 degrees.
Sine and cosine are complementary, which means when they are added together, the equal 90. So, to find sine, subtract 53 from 90, to get x = 37.
Here is an image to show this.
I hope this helps!
Answer is b ,-4x^2 - 13y^2
The formula to find the volume is 1/2(l*w*h)
Height= 7.6
Width=9
Length=13
So, 1/2(7.6*9*13) and you will get the answer
