Brittany's kite is flying above a field at the end of 65 m of string. If the angle of elevation to the kite measures 70°, how high is the kite above Brittany's head?

61.1 m is the correct answer.

Step-by-step explanation:

Given that

Brittany's kite has a string length = 65 m

Angle of elevation of kite =

A right angled triangle can be constructed for the given situation.

Please refer to the attached figure.

in which B is the position of Brittany.

K is the position of kite and

F is the point of field above which the kite is flying.

Given that the side BK = 65m

To find, side FK = ?

We can use sine trigonometric identity to find the value of FK.

We know that :

Hence, the answer is 61.1 m.
