From the top of a vertical pole a boy observe a ball on the ground at an angle of depression of 65 degree if the distance from the ball to the foot of the pole is 10m find the distance of the ba ok l to the boy

Answer 1

90-65 = 25
sin 25 = 10 / hypotenuse
hypotenuse = 10 / sin 25

Answer 2

since the angle of depression from the boy to the ball is the same as the angle of elevation from the ball to the boy,
h = 10/sin65°
