A ladder 15 m long just reaches the top of a vertical wall. If the ladder makes an angle of 60° with the wall, then the length of the wall is:

A. 15 √3 m
B. 15 √2 m
C. 15/2 m
D. 15 √7 m

Explanation: Using trigonometry, the length of the wall is 15 √3 meters.

The angle of depression of a point situated at a distance of 70m from the base of a tower is 60°. The height of the tower is:

a. 35√3 m
b. 70√3 / 3 m
c. 70 m
d. 70√3 m

Explanation: Using the tangent function, the height can be calculated as 70 * √3 / 2 = 35√3 meters.
