6.perimeter of the given shape above is
avanturin [10]
The answer is B.

One side is 14 feet and the other is 6. Since it is a rectangle and a rectangle has four sides, we need to take 14 and multiply it by 2. That will get us 28. Same thing apply for the other side. 6 multiplied by 2 is 12. And if we take our 2 numbers which are 28 and 12 and we add them up, our Perimeter is 40.

Hope this helps and if it does, don't be afraid to rate my answer as well as maybe give it a "Thanks"? (Or even better a "Brainliest"). And if it’s not correct, I am sorry for wasting your time, and good luck finding the correct answer :)

How do you find endpoints of a line segment with a given endpoint and midpoint?
seraphim [82]

In order to find the second endpoint or a line segment given the first and the midpoint, you need to realize that the midpoint is an average of the two endpoints. Given that fact, we can derive this formula looking at x values of points A and B with midpoint M. Remember this is only looking at the x values.

(A + B)/2 = M

So if we are looking for A, we can solve for A and use this modified formula.

(A + B)/2 = M

A + B = 2M

A = 2M - B

Now we can do this with the y values of these points as well. We then have the coordinates of both parts of A.

In a right triangle, CosA=0.352 and SinA=0.936 What is the approximate value of tanA?
mr_godi [17]
\tan A=\frac{\sin A}{\cos A}

Proof: \sin\div\cos=\frac{o}h\div\frac{a}h=\frac{o}h\times\frac{h}a=\frac{oh}{ha}=\frac{o}a=\tan

\cos A=0.352,\ \sin A=0.936

\tan A=\frac{0.936}{0.352}

\boxed{\tan A=2.65\overline{90}} <em>(round as needed)</em>
