By using this;
H=u^2 sin^angle/2g we can get the answer.
H=u^2 sin^angle/2g we can get the answer.

H=u^2 sin^2angle/2g.
5.54=60^2sin^2angle/(2*9.81),
after solving this angle is 10.00650.
So, the answer is 10.
5.54=60^2sin^2angle/(2*9.81),
after solving this angle is 10.00650.
So, the answer is 10.

By putting formula for maximum height. We can find the angle.

This is a projectile motion how can we use this equation. The equation of max height of the projectile is (v^2sin^2angle)/(2g) right?

The answer is required for maximum range, not for maximum height.
For the Maximum range (149.413 m) the angle must be 12 degrees.
Range values for other given angles are less than the range occupied if the angle of trajectory is 12 degrees.
