Answer:
[tex]h = 63.92\ m[/tex]
Step-by-step explanation:
Given:
Angle of elevation = 70°
Length of string = 68 m
We need to find the height of the kite.
Solution:
Requirement figure attached in file.
Where:
BC = 68 m
AC = h (Height of the kite)
∠ABC = 70°
Using Cosine rule to find the height of the kite.
[tex]AC = BC\times sin(70)[/tex]
[tex]h = 68\times 0.94[/tex]
[tex]h = 63.92\ m[/tex]
Therefore, height of the kite from Brian's head [tex]h = 63.92\ m[/tex].
