A kite with a string 80 feet long makes an angle of elevation of 40° with the ground, assuming the string is straight, how high
defon
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.

sin(x)= \frac{opp}{hyp}
sin(40)= \frac{x}{80}
80sin(40)=x
x=51.42 rounded to two decimal place

Perpendicular height of the kite from the ground is 51.42 feet

Rewrite the following expression using the properties of rational exponents. Be sure your answer is in simplest form.
Nookie1986 [14]

Answer:

(2\cdot 6)^{\frac{3}{2}}=24(3)^{\frac{1}{2}}

Step-by-step explanation:

The given expression is (2*6)^{\frac{3}{2}}

We multiply within the parenthesis to get:

(12)^{\frac{3}{2}}

Recall that: a^{\frac{m}{n} } =\sqrt[n]{x^m}

We apply this property to get:

(12)^{\frac{3}{2}}=\sqrt{12^3}

(12)^{\frac{3}{2}}=\sqrt{12^2*12}

This simplifies to

(12)^{\frac{3}{2}}=12\sqrt{12}

We can simplify further

(12)^{\frac{3}{2}}=12\sqrt{4*3}=12*2\sqrt{3}=24\sqrt{3}

We rewrite as rational exponent  24(3)^{\frac{1}{2}}
