Q1:

The angle of elevation to the top of a skyscraper from a 30 m high house is 5 8 4 2 ′ ∘ . The base of the house is 45 meters away from the base of the skyscraper. Find the height of the skyscraper giving the answer to two decimal places.

Q2:

Two points on the ground lie collinearly on either side of a flagpole 29 meters tall. The angles of elevation from the two points to the top of the flagpole are 4 5 1 8 ′ ∘ and 3 4 1 8 ′ ∘ . Find the distance between the two points giving the answer to one decimal place.

Q3:

A man was standing on the ground 28 m away from the base of a tower that had a flagpole on its top. He measured the angles of elevation of the top and the base of the flagpole and found them to be 4 3 3 0 ′ ∘ and 2 2 1 2 ′ ∘ respectively. Find the height of the flagpole giving the answer to the nearest meter neglecting the height of the man.
