Mathematics Practice Test – Angles of Elevation and Depression

The angle of elevation of the top X of a vertical pole from a point P on a level ground is 60^o. The distance from P to the foot of the pole is 55 m. Without using tables, find the height of the pole.

A.  m

B. 50 m

C. 55  m

D.  m

A ladder leans against a vertical wall at an angle 60^o to the wall. If the foot of the ladder is 8m away from the wall, calculate the length of the ladder.

A. 8 m
B. 12 m
C. 16 m
D. 18 m

In the fig. above, points B and C are on a horizontal plane and |BC| = 30 cm. A and D are points vertically above B and C respectively. |DC| = 40 m and |AB| = 26 cm. Calculate the angle of depression of A from D correct to the nearest degree
