The shadow of a vertical tower is 50 m long when the angle of elevation of the sun is 35°. find the height of the tower. © k12 inc. 2. an airplane is flying 12,330 feet above level ground. the angle of depression from the plane to the base of a building is 11°. how far must the plane fly horizontally before it is directly over the building?

1.  To find the shadow of the tower, you must calculate the tangent of 35. Tan. (35) = x/ 50. X= tan (35) (50) = 35. The tower is 35 m.

2. To find how far the plane must fly, you must calculate the tangent of 11. Tan. (11) = 12,330 / x. X = 12,330/ tan (11). X = 63,432. The plane must fly 63,432 feet before it is directly over the building.

Hope this helps.

Skew lines(segments) are lines(segments) in 3 dimensions that do not intersect the given segment and are not parallel to it.  ae, bf, eg, and fh are your skew segments.  i hope that : )
