What is the simplified form of ?

Natalija [7]

Let's set it up like this:
$\frac{\frac{x}{3}-\frac{y}{4}}{\frac{x}{4}+\frac{y}{3}}$
Find the LCD, which is 12, and adjust them according to that.
$=\frac{\frac{4x-3y}{12}}{\frac{3x+4y}{12}}$
Divide.
$=\frac{\left(4x-3y\right)\cdot \:12}{12\left(3x+4y\right)}$
Cancel the common factor, which is 12.
$=\frac{4x-3y}{3x+4y}$
That would be our answer!

Let me know if you have any questions regarding this problem!
Thanks!

A 50 ft flagpole is mounted to the top of a building. If the angle of elevation from a spot on the street to the top of the pole

Answer:

the height of the building = 91.67161722 feet.

Step-by-step explanation:

Suppose the height of the building (BC) = X feet.

A 50 ft flagpole (AB) is mounted to the top of a building.

So, height of the top of flag above the ground (AC) = (X+50) feet.

If the angle of elevation from a spot (P) on the street to the top of the pole is 58 degrees and the angle of elevation from the same spot (P) to the bottom of the pole is 46 degrees.

It means ∠APC = 58° and ∠BPC = 46°.

Considering Right triangle ΔACP, cot(∠APC) = PC / AC.

PC = AC*cot(∠APC) = (X+50)*cot(58°)

Considering Right triangle ΔBCP, cot(∠BPC) = PC / BC.

PC = BC*cot(∠BPC) = X*cot(46°)

We have PC = PC.

X*cot(46°) = (X+50)*cot(58°)

0.965688774 * X = 0.624869351 * (X+50)

(0.965688774 - 0.624869351) * X = 0.624869351 * 50

0.340819422 * X = 31.2434676

X = 31.2434676 / 0.340819422 = 91.67161722 feet.

Hence, the height of the building = 91.67161722 feet.
