10.) Kelly is flying a kite to which the angle of elevation is
70°. The string on the kite is 65 meters long. How far is the
kite above the ground?

Answer:

61.08m

Step-by-step explanation:

Let " l " be the length of the rope and " θ " the angle at which it is raised. In other words:

  • l = 65m
  • θ = 70°

As you can see, there has been made a right angle triangle. So:

[tex]sin70 = \frac{h}{l} \\ h = l \times sin70 \\ h = 65 \times 0.9397 = 61.08 \\ h = 61.08[/tex]

So the kite is approximately 61.08m above the ground.

In order to find the sin70° i used a calculator.
