Answer:
∠ 3 = 63°
Step-by-step explanation:
∠ 2 and ∠ 3 are adjacent angles and supplementary, thus
∠ 2 + ∠ 3 = 180°, that is
117° + ∠ 3 = 180° ( subtract 117° from both sides )
∠ 3 = 63°
The height of the kite is 4.89 feet
Explanation
The length of the line attached to the kite=7 feet
The length of the shadow that is cast on the ground=5 feet
the system forms a right angled triangle where the taught string of the kite is the hypotenuse, the shadow is the base and the height of the kite above the ground is the height.
H=7 feet
b=5 feet
using pythagoras theorem

The kite is 4.89 feet above the ground
