Find cot theta if csc theta = <br><br>sqrt17/4 and tan theta >0.

Lorico [155]

Answer:

$tan \theta = 4$

Step-by-step explanation:

We know that

$cosec \theta = \frac{hypotenuse }{opposite }$

Given :

$cosec \theta =\frac{\sqrt{17}}{4}\\$

So 4 is the opposite side of theta.

$tan \theta = \frac{opposite}{adjacent}$

We use the Pythagorean theorem to find for the adjacent side.

$a = \sqrt{17 - 4^2} = \sqrt{17-16} = 1$

$Therefore, \ tan \theta = \frac{4}{1} = 4$

The length of a rectangle is twice its width<br> The perimeter of the rectangle is 43cm

boyakko [2]

Answer:

7.17 cm

Step-by-step explanation:

If the width is x, the length is twice this = 2x

And

Perimeter = 2 (W + L)

Perimeter = 2 ( x + 2x)

Perimeter = 2 (3x)

Perimeter = 6x

43 = 2 ( x + 2x )

43= 2 ( 3x)

43 = 6x

= 7.17 cm

Hope this helps i'm pretty sure this is how you do it :-)
