Answer:
45 feet.
Explanation:
sin(θ) is the ratio of the opposite side to the hypotenuse
opposite side is the height and hypotenuse is the length of the string
100 Sin 25 gives the height from the hand.
100 x sin25 = 100 x 0.4226 = 42.26 feet from the hand.
Since the hand is 3 feet above the ground height is = 3+ 42.26 ≅ 45
