Answer:

34.78 feet

Step-by-step explanation:

1) using the cosine function, I did cos(43)=x/51

This is because cosine is equal to adjacent over hypotnuse

Once I found x, I used the pythagorean theorem to get 34.78 feet

PLEASE HELP MEEEEEEEEEEEEE

Answer: 20 ft

Step-by-step explanation:

The mirror is set away from the flagpole on the same scale set away from her.

The distance she stand's away from the mirror is 1/4 of the length of the distance between the mirror and the flag pole because she's 1/4 of the flagpole's size.

This means her size x4 is the size for the flag pole. This checks out because 12x4=48

So to find the height we must do 5x4

5x4=20

Solve for e. T=e29<br><br><br> ​​ e=±3T√T<br><br> e=±3T<br><br> e=±3T√<br><br> ​ e=±9T√ ​

Answer:

option (3) is correct.

e= \pm 3\sqrt{T}

Step-by-step explanation:

Given T=\frac{e^2}{9}

We have to solve for e.

Consider the given statement,

T=\frac{e^2}{9}

Cross multiply, we get,

\Rightarrow 9T={e^2}

Taking square root both sides , we get,

\Rightarrow \sqrt{9T}=e

We know square root of 9 is 3.

\Rightarrow \pm 3\sqrt{T}=e

Thus, option (3) is correct.

e= \pm 3\sqrt{T}
