For which value of theta is cot theta equal to cos theta?

Answer:

\frac{cos \theta}{sin \theta}= cos \theta

If we multiply by cross we got:

cos \theta = sin \theta cos \theta

We can divide both sides of the last equation by cos \theta and we got:

sin \theta = 1

And if we apply arcsin in both sides we got:

\theta = arcsin (1) = \frac{\pi}{2}

And the best solution would be:

C) pi/2

Step-by-step explanation:

For this case we want to solve the following equation:

cot \theta = cos \theta

And we know that by definition cot \theta = \frac{cos \theta}{\sin \theta}

And replacing we got:

\frac{cos \theta}{sin \theta}= cos \theta

If we multiply by cross we got:

cos \theta = sin \theta cos \theta

We can divide both sides of the last equation by cos \theta and we got:

sin \theta = 1

And if we apply arcsin in both sides we got:

\theta = arcsin (1) = \frac{\pi}{2}

And the best solution would be:

C) pi/2

A betta fish tank is in the shape of a cube. The volume of the fish tank is 216
GarryVolchara [31]

To find this answer, we need to understand how to get the Volume.

We get the volume by the formula: L x W x H

L = Length

W = Width

H = Height

So, we can see that there are 3 units required to know for getting the volume, if that's true, then, to do the inverse operation of finding the volume. That can be done by using thie formula:

V=a^3

a= edge

Solving for a

a=V⅓=216⅓=6

<h2>So hence, each of the Cube shaped Fish Tank is 6in³</h2>

now, let's look at how to find whether our answer is right or wrong

6x6=36

36x6=216

So hence, our answer is right!

(WILL GIVE BRAINLIST TO BEST ANSWER) What’s the missing angle based on the given angle measures.
matrenka [14]

Answer:

∠3 = 107°

Step-by-step explanation:

Similar to the other question, ∠3 and ∠4 are supplementary and add up to 180 degrees as they make up the entirety of a straight line.

∠4 is 73°, so ∠3 has to be 107°.
