A Girl Guide measured the angle of elevation to the top of a monument to be 59°. The height of the monument is 38.5 m. She
then walked 31.0 m farther away from the tower. Determine the angle of elevation to the top of the monument from her new
location, to the nearest tenth of a degree.

Answer 1

The angle of elevation is 35.4.

What is angle of elevation?

The angle formed by the line of sight and the horizontal plane for an object above the horizontal.

tan D = AB/BD

tan D = 38.5/54.13

D = 35.4

Hence, the angle of elevation is 35.4.
