The string of a kite is 120 metres long and it makes an angle of 60 degree
Afina-wow [57]

Answer:

103.92 m

Step-by-step explanation:

The kite is making right angle with the ground and its string is acting as hypotenuse of right triangle.

Let the height of the kite from the ground be h meters.

Therefore, by trigonometrical ratio:

\sin \theta \:  =  \frac{height \: of \: the \: kite}{length \: of \: the \: string}  \\  \\  \sin 60 \degree \:  = \frac{h}{120}  \\  \\  \frac{ \sqrt{3} }{2}  =  \frac{h}{120}  \\  \\ h =  \frac{ \sqrt{3} }{2}  \times 120 \\  \\ h =  \sqrt{3}  \times 60 \\  \\ h = 1.732 \times 60 \\  \\ h = 103.92 \: m \\

Thus, the height of the kite from the ground is 103.92 meters.

The following chart shows a store’s coat sales for two years.
STALIN [3.7K]

Answer:

Sales of trench coats increased 8.3 percentage points faster than total coat sales.

Step-by-step explanation:

<u>2006:</u>

top coats is 297,

parkas is 210,

jackets is 213,

raincoats is 137,

trench coats is 103

Total: 297+210+213+137+103=960

<u>2007:</u>

topcoats is 223,

parkas is 210,

jackets is 285,

raincoats is 259,

trench coats is 127

Total: 223+210+285+259+127=1,104

<u>Percent increase in total sales:</u>

\dfrac{1,104-960}{960}\cdot 100\%=15\%

<u>Percent increase in sales of trench coats:</u>

\dfrac{127-103}{103}\cdot 100\%\approx 23.3\%

Since 23.3\%-15\%=8.3\%, sales of trench coats increased 8.3 percentage points faster than total coat sales.
