Angles of Elevation and Depression with Special Right Triangles From the top of a 7 meter tall building, the angle of elevation to the top of a cable tower is 60 and the angle of depression to the base of the cable tower is 45. Use the properties of special right triangles to find the height of the tower. E The exact height of the tower is meters. The approximate height of the 60 45 tower (rounded to the nearest 10th) is meters C
