Solution



If the angle of elevation of the top of a hill from each of the vertices A, B and C of a horizontal triangle is \alpha, then the height of the hill is





Go to Discussion


Solution



A tower subtends angles \alpha, 2\alpha and 3\alpha respectively at points A, B and C which are lying on a
horizontal line through the foot of the tower. Then \frac{AB}{BC} is equal to

Solution



A tower subtends an angle of 30° at a point on the same level as the foot of the tower. At a second point h meters above the first, the depression of the foot of the tower is 60°. What is the horizontal distance of the tower from the point?





Go to Discussion


Solution



From three collinear points A, B and C on a level ground, which are on the same side of a tower, the angles of elevation of the top of the tower are 30°, 45° and 60° respectively. If BC = 60 m, then AB is:
