In analytical geometry, there are already derived equations to find the distance of lines and points as well as the angle made between two lines. As special case is when the other line is one of the coordinate axis. Then, the formula can be simplified to

tan θ =m, where m is the slope of the equation

In the next step, we also incorporate operations of calculus. Since the slope is equal to Δy/Δx, this is equivalent to dy/dx in calculus. Therefore, you can find the slope by differentiating the equation in terms of x.

<span>y-2x=7
y = 2x+7
dy/dx = 2 =m

So,

tan </span>θ = 2
θ = tan⁻¹(2)
θ = 63.43°

joanna can buy 15 square yards of carpet for $240 using the same rate how many square yards of carpet can she buy for $320​
Sladkaya [172]

Answer:

x =20

Step-by-step explanation:

We can use proportions to solve

$240         320

----------- = ------------

15                x

Using cross products

240x = 320 * 15

240x =4800

Divide by 240 on each side

240x/240 = 4800/240

x =20
