Question

A a projectile is thrown at an angle 37 degree from the vertical angle of elevation of the highest point of the projectle from the point of projection is

Answer 1

Answer:

Explanation:

Angle of elevation from height point will be tan-1(2/3)

For explanation please see the image.

Answer 2

Answer:

tan-1(2/3) is the angle of elevation.

Explanation:

We let the angle of elevation to be x since the projectile makes an angle of 37 degree with the vertical hence the angle with the horizontal will be 53 degree.

We know the formulae of the angle of elevation will be x = tan-1((tan53)/2) which on solving we will get the angle of elevation to be x = tan-1 ( 2/3) where the value of tan53 will is 4/3.
