Find cot theta if csc theta= the square root of 5/2 and tan theta>0

Nostrana [21]

Since $\cot^2\theta+1=\csc^2\theta$ , you have

$\cot^2\theta=\left(\dfrac{\sqrt5}2\right)^2-1=\dfrac14$
$\cot\theta=\pm\sqrt{\dfrac14}=\pm\dfrac12$

Since $\tan\theta>0$ , and $\cot\theta=\dfrac1{\tan\theta}$ , you know that $\cot\theta$ is also positive, which means

$\cot\theta=\dfrac12$

1) the answer is 2, 12 - 4x = 2x, x=2.
2) x + (x+5) = 17, 2x = 12, x=6.
3) x + (3x-60) = 1220, 4x = 1280. So Fred, x, made $320. Frank made $900.

Solve the equation with all steps.<br><br> 3/2x-2/3x=2

wolverine [178]

Answer:

$x = \frac{5}{12}$

Step-by-step explanation:

$\frac{3}{2x} - \frac{2}{3x}$

➡️ $\frac{3}{2x} - \frac{2}{3x} = 2$

➡️ $\frac{5}{6x} = 2$

➡️ $5 = 12x = 12x = 5$

➡️ $x = \frac{5}{12}$
