The range R and the maximum height H of a projectile fired at an inclination θ
to the horizontal with initial speed v0
are given by the formulas​ below, where g≈32.2 feet per second per second is the acceleration due to gravity.

R≈1369.5652

Find the range H if the projectile is fired at an angle of 45° to the horizontal with an initial speed of 210 feet per second.​
