Grayson is flying a kite, holding his hands a distance of 2.75 feet above the ground and letting all the kite’s string play out.

sergiy2304 [10]

The position of the kite with the point directly beneath the kite at the same

level with the hand and the hand for a right triangle.

The height of the kite above the is approximately 66.314 feet.

Reasons:

The height of his hands above the ground, h = 2.75 feet

Angle of elevation of the string (above the horizontal), θ = 26°

Length of the string, l = 145 feet

Required:

The height of the kite above the ground.

Solution:

The height of the kite above the ground is given by trigonometric ratios as follows;

$\displaystyle Height \ of \ kite, \, k_h = \mathbf{h + l \times sin(\theta)}$

Therefore;

$\displaystyle Height \ of \ kite, \, k_h = 2.75 + 145 \times sin(26^{\circ}) \approx \mathbf{66.314}$

The height of the kite above the, $k_h$ ≈ 66.314 feet

Rewrite as a simplified fraction.

Mnenie [13.5K]

Answer:

$\bold{x = \dfrac{8}{9}}$

Step-by-step explanation:

We have to rewrite the below as simplified fraction.

$\large{0.\overline{8} = {?}}$

Solution:

Let $x =0.\overline 8$ which means $x =0.888888.......$

Here a bar over 8 means that there the given decimal value is non terminating and there are a large numbers of 8 present after the decimal.

To solve the given non terminating decimal as fractions, we will have to eliminate the bar term from the given value.

So, we can rewrite $x$ as:

$x =0.8\overline8$ ......(1)

Now, let us multiply the above with 10.

$10x = 0.8\overline 8 \times 10\\\Rightarrow 10 x= 8.\overline8$ ....... (2)

Now, let us subtract (1) from (2):

$10x-x=8.\overline8 - 0.\overline8\\\Rightarrow 9x = 8\\\Rightarrow \bold{x = \dfrac{8}{9}}$

So, in simplified fractions:

$\large{0.\overline{8} = \bold{\dfrac{8}{9}}}$
