Robin is flying a kite. She ties the 50 foot kite string to the ground. If the kite is

krok68 [10]

$\bold{\huge{\orange{\underline{ Solution }}}}$

<h3>Given :-</h3>

We have given in the question that, Robin is flying a kite.
She ties the 50 foot kite string to the ground .
The kite is flying at 40 feet high

We have to find the measure of the angle the string forms with the group that is angle of elevation.

<h3>Let's Begin :-</h3>

According to the given question,

Hypotenuse AC ( Distance of string from the ground) = 50 ft.
Perpendicular height AB ( Distance of the kite from the ground) = 40 ft.

<h3>Therefore, </h3>

By using trigonometric ratios,

{ $\bold{\pink{ Sin Φ = }}{\bold{\pink{\dfrac{Perpendicular}{Hypotenuse }}}}$

$\bold{\red{ Cos Φ = }}{\bold{\red{\dfrac{Base}{Hypotenuse }}}}$

$\bold{\purple{ Sin Φ = }}{\bold{\purple{\dfrac{Perpendicular}{Base }}}}$ }

The Angle of elevation will be 

[ The angle that is formed between the line of sight and base of the triangle is called angle of elevation ]

$\bold{\pink{Sin Φ = }}{\bold{\pink{\dfrac{AB}{AC }}}}$

$\sf{ Sin Φ = }{\sf{\dfrac{40}{50 }}}$

$\sf{ Sin Φ = }{\sf{\dfrac{4}{5}}}$

$\sf{ Sin Φ = 0.8 }$

$\bold{\green{ Φ = 45.83° }}$

Hence, The measure of the angle the string forms with the ground is 45.83° .

Answer:

Step-by-step explanation:

1. Proportion.

$\frac{3}{7.5}$ = $\frac{1}{x}$

2.Lets cross multiply.

$3x=7.5$

3.Solve

$3x=7.5\\divide 3x -on- both-sides\\\\$

________________

$x=2.5$

$1=2.5\\1:2.5$
