“Airborne minimum takeoff angle”

Q:

A vehicle becomes airborne and travels through the air 20 feet
horizontally and impacts a building 3 feet higher than where it
took off. What is the takeoff angle (in degrees) that will give the
minimum speed of the vehicle to achieve that airborne trajectory?
(Hint: the y-axis points down (in the direction of gravity) in the
derivation of the airborne formulas.)
