Step-by-step explanation:

Given

--- altitude

--- horizontal distance

Required

The angle of elevation

The question is illustrated with the attached image.

From the attachment,

This gives:

Take arctan of both sides

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.
