Word Problems for Right Triangle Trig

Angle of Elevation: The angle above the horizontal that an observer must look at to see an object that is higher than the observer.

Angle of Elevation: The angle above the horizontal that an observer must look at to see an object that is higher than the observer.

Angle of Depression: The angle of depression is the angle below the horizontal that an observer must look to see an object that is lower than the observer.

Angle of Depression: The angle of depression is the angle below the horizontal that an observer must look to see an object that is lower than the observer.

A man is walking along a straight road. He notices the top of a tower at an angle of elevation A = 60 o with the ground at the point where he is standing. If the height of the tower is h = 30 m, then what is the distance (in meters) of the man from the tower?

A little boy is flying a kite. The string of the kite makes an angle of elevation of 70 o with the ground. If the height of the kite is h = 24 m, find the length (in meters) of the string that the boy has used.

Two towers face each other separated by a distance d = 40 ft. As seen from the top of the first tower, the angle of depression to the second tower's base is 55 o and to the top of the second tower is 23 o. What is the height (in ft) of the second tower?
