Answer:
Using sine ratio:
As per the statement:
The angle of elevation from Sara to kite in the sky is 53° and the length of the string is 32 feet. and Sara is 5 feet tall.
⇒Angle of elevation( ) = 53° and
Hypotenuse side = 32 feet (As you can see the figure as shown below)
then;
Apply the sine ratio in triangle ACE we have;
Multiply both sides by 32 we get;
Simplify:
CE = 25.5563363215 feet.
Then:
DE = CD+CE = 5 + 25.5563363215 = 30.5563363215 ≈30.6 feet.
Therefore, 30.6 feet far off the ground is the kite.
