1.The angle of elevation of the top of a flagpole from a point on level ground is 30°. From another point on the ground, 20m nearer the flagpole the angle of elevation is 60°. Calculate the height of the flagpole. 2. The angle of depression of a point on the 225m contour line is 10.2°, from the top of a hill 915m high. Calculate the horizontal distance between the two points. Find the difference between this distance and the actual distance between the two points 3. A boy standing 70m away from a flag-post observes that the angles of elevation of the top and bottom of a tower on the top of the flag post are 57° and 69° respectively. Find the height of the tower. |

Check your question 2. Seems there is an ambiguity in the question. The two points you are talking about, is it the top of the hill and the point on the contour line? If that is the case, shouldn't it be vertical distance? Feed me back on question 2 @Tahtah attached are solutions to 1 and 3 1 Like
