10! If you use the trapezoid area formula and plug in the known values, just solve for h(height)
Answer:
Perpendicular to base
Step-by-step explanation:
The cut creates two rectangular prisms (each angle must be 90 degrees)
The cut is perpendicular to the base
We have a point and a slope, so let's use the point slope formula!

where
x1=4
y1=2
and m=3
The answer is going to be x=22
