Question 1
Two buildings are 100m apart. If a person stands at the midpoint and sees the top of both buildings at angles of elevation 30° and 45°, find the heights of both buildings.
💡 Hint: Use tan = Opposite/Adjacent to find both heights based on the angles given.
Question 2
On a triangular plot of land, the length of one side is 100 m, and the angle between that side and the other two sides is 60°. Calculate the lengths of the other two sides.
💡 Hint: Remember, a² = b² + c² - 2bc*cos(A).
