Answer:

The answer is " $\bold{17456.6 \ ft}$ "

Step-by-step explanation:

Please find the complete question in the attached file.

$\sin \theta = \frac{P}{h}\\\\\to BC =x\\\\\to BD =y\\\\$

The height of tower (AB) = 300 ft

Distance = CD

$\Delta ABC \\\\\sin \theta = \frac{AB}{AC}\\\\\sin (2.5) = \frac{300}{AC}\\\\Ac= \frac{300}{\sin (2.5)}\\\\AC= 6877.68 \\\\\Delta ABD \\\\\sin \theta = \frac{AB}{AD}\\\\\sin (1.3) = \frac{300}{AD}\\\\AD= \frac{300}{\sin (1.3)}\\\\AC= 1322.33$

calculating CD :

$CD^2 = AC^2 +AD^2 -2\cdot AC \cdot AD \cdot \cos(117^{\circ}) \\\\CD = \sqrt{(6877.68)^2 +(13223.23)^2 -2\cdot (6877.68) \cdot (13223.23) \cdot \cos(117^{\circ})}\\\\CD =\sqrt{47302482.1824 + 174853811.6329 - 82576463.207}\\\\CD= \sqrt{304732757.02}\\\\CD= 17456.6 \ ft$

An equation allows you to find the x- and y-coordinates of any point on the xy-plane.

monitta

Answer:

The give statement is true.

Step-by-step explanation:

Yes, we can find the coordinates of any point on the xy-plane for any given equation.

For the given equation, we can take random values of x and then find the corresponding y values.

Let us prove this statement with an example.

Let us suppose, we have the equation $y=x^2+4$

For x= 1, we have

$y=1^2+4\\\\y=5$

Thus, the coordinate of the point is (1,4)

Similarly for other values of x, we can find the y values and can find the coordinate.

Thus, we can say that an equation allows us to find the x- and y-coordinates of any point on the xy-plane.
