If tan θ=3\4 , find csc

Rom4ik [11]

In a rectangular triangle $\tan\theta\dfrac{opposite}{adjacent}$ .

We have $\tan\theta=\dfrac{3}{4}$

Therefore opposite = 3uints and adjacent = 4units.

$\csc\theta=\dfrac{hypotenuse}{opposite}$

We need the length of hypotenuse.

Use the Pythagorean theorem:

$h^2=3^2+4^2\\\\h^2=9+16\\\\h^2=25\to h=\sqrt{25}\to h=5units$

Substitute:

$\csc\theta=\dfrac{5}{3}$

What is the slope of th line that contains the points (-1, 8) and (5, -4)

In-s [12.5K]

so you just do the slope formula

which y2-y1 over x2-x1 in fraction form

so you would do

(-1 , 8) (5 , -4)

(x1 , y1) (x2 , y2)

-4 - 8 over 5- (-1)

which would give you the fraction 12/6

it can be simplified to 2

so 2 is your slope

hope it help
