the distance around tims rectangulr book is 48 centimeters the length of each longer side is 14 cm what is the length of each sh

yanalaym [24]

let the length of each shorter side be x

length of longer side= x+14

2(x+14) + 2x = 48

2x + 28 + 2x = 48

4x + 28 = 48

4x = 48-28

4x = 20

x = 5

shorter side = 5cm

Use the given information to determine the exact trigonometric value.<br> (in the image attached)

notka56 [123]

Answer:

OPTION B: $\frac{-2\sqrt{5}}{5}$

Step-by-step explanation:

Given $cot \theta = -\frac{\sqrt{5}}{2}$

We know that, $\frac{1}{cot \theta} = tan \theta$

$\implies tan \theta = \frac{1}{-\frac{\sqrt{5}}{2}}$

$= -\frac{2}{\sqrt{5}}$

Multiplying and dividing by $\sqrt{5}$ , we get:

$tan \theta = - \frac{2 \sqrt{5}}{\sqrt{5}\times \sqrt{5}}}$

$\implies tan \theta = -\frac{2\sqrt{5}}{5}$

Hence, OPTION B is the answer.
