Step-by-step explanation:

Answer: The volume of largest rectangular box is 4.5 units.
Step-by-step explanation:
Since we have given that
Volume = 
with subject to 
So, let 
So, Volume becomes,

Partially derivative wrt x and y we get that

By solving these two equations, we get that

So, 
So, Volume of largest rectangular box would be

Hence, the volume of largest rectangular box is 4.5 units.
IGH because the angles line up
A straight line is 180 degrees. To get x, you subtract 117 from 180.
180-117 is 63.
x= 63.
x+y is 90 degrees so to find y, you subtract x from 90.
90-63 is 26.
y=27.
