100 POINTS! PLEASE HELP!

Semmy [17]

Apply angle bisector theorem

$\\ \sf\longmapsto \dfrac{9}{15}=\dfrac{3}{5}=\dfrac{2x-1}{3x}$

$\\ \sf\longmapsto 9x=5(2x-1)$

$\\ \sf\longmapsto 9x=10x-5$

$\\ \sf\longmapsto 10x-9x=5$

$\\ \sf\longmapsto x=5$

$\\ \sf\longmapsto \dfrac{4}{3}=\dfrac{x}{2.25}$

$\\ \sf\longmapsto 4(2.25)=3x$

$\\ \sf\longmapsto 3x=9$

$\\ \sf\longmapsto x=3$

Hope it helps

The angle of elevation from the top of a house to a jet flying 2 miles above the house is x radians. If d represents the horizon

alisha [4.7K]

Answer:

d = 2cot(x) or d = 2/tan(x)

Step-by-step explanation:

The vertical distance from the jet to the top of the house represents the opposite side to the 'x' angle, while the horizontal distance, d, represents the adjacent side. Since we do not know the hypotenuse, the tangent and cotangent functions are the preferable choices:

$tan (x) = \frac{2}{d}\\d = \frac{2}{tan (x) }\\cot (x) = \frac{d}{2} \\d= 2cot(x)$

Therefore, the distance 'd' can be expressed as d = 2cot(x) or d = 2/tan(x).
