Use the diagram and complete the steps to find the measure of the angle of depression from the top of the hoop to Lisa.
The length of the shortest leg of the right triangle that is formed is A. 3.5 B. 8.5 C.12 feet.
The angle of depression from the hoop to Lisa is A. Complementary B. Congruent C. Supplementary to the angle of elevation from Lisa’s line of sight to the hoop.
Because the lengths of the opposite and adjacent sides are known, use the A. Inverse Cosine B. Inverse Sine C. Inverse Tangent function.
The angle of depression, rounded to the nearest degree, is approximately A. 19 B. 21 C. 71 degrees.

To Find : The length of the shortest leg of the right triangle that is formed is A. 3.5 B. 8.5 C.12 feet.
The angle of depression from the hoop to Lisa is A. Complementary B. Congruent C. Supplementary to the angle of elevation from Lisa’s line of sight to the hoop.
Because the lengths of the opposite and adjacent sides are known, use the A. Inverse Cosine B. Inverse Sine C. Inverse Tangent function.
The angle of depression, rounded to the nearest degree, is approximately A. 19 B. 21 C. 71 degrees.
Solution:
Right angle triangle formed 8.5 = 3.5 ft and 10 ft ( perpendicular sides)
Hypotenuse = √10² + (3.5)² = 10.595 ft
The length of the shortest leg of the right triangle that is formed is 3.5 feet
The angle of depression from the hoop to Lisa is Congruent to the angle of elevation from Lisa’s line of sight to the hoop.
to find the measure of the angle of depression from the top of the hoop to Lisa use the Inverse Tangent function.
Because the lengths of the opposite and adjacent sides are known, use the Inverse Tangent function.
angle of depression = tan⁻¹(3.5/10) = 19.29° = 19°
The angle of depression, rounded to the nearest degree, is approximately 19°
