The diagram of the kite is shown below
To find the perpendicular height of the kite from the ground, we use the trigonometry ratio for sin(x).
The reason for using the sine ratio is because we have the hypotenuse, 80 feet, and the angle, 40° and we are looking for the length of the side opposite the angle.




rounded to two decimal place
Perpendicular height of the kite from the ground is 51.42 feet
Answer:

Step-by-step explanation:
The given expression is 
We multiply within the parenthesis to get:

Recall that: ![a^{\frac{m}{n} } =\sqrt[n]{x^m}](https://tex.z-dn.net/?f=a%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%20%7D%20%3D%5Csqrt%5Bn%5D%7Bx%5Em%7D)
We apply this property to get:


This simplifies to

We can simplify further

We rewrite as rational exponent
