Find the total area for the pyramid with the equilateral base.<br><br><br><br> T. A. =
iogann1982 [59]

Answer:

36√3 + 144

Step-by-step explanation:

Given that,

base of the pyramid is an equilateral triangle with sides = 12

Formula to calculate total surface area of pyramid

<h3>[Base Area] +  1/2 × Perimeter × [Slant Length]</h3>

Base Area

1/2 (height) (base)

1/2 (√12²-6²)(12)

6(6√3)

36√3

perimeter of base

sum of all sides = 12 + 12+ 12

                          = 36

slant height = √10²-6²

                     = 8

put all these values in the formula above

36√3 + 1/2(36)(8)

36√3 + 144

Total area for the pyramid with the equilateral base =

36√3 + 144

The quotient if 4÷7 is a decimal number.How many digits in the quotient are overlined
Licemer1 [7]

I'm assuming by overlined you meant repeating as when there is a repeating number in a decimal, it has a line over it to represent such.

In the quotient of 4 divided by 7, there are zero numbers overlined. This is because the answer is .5714285714, no numbers are consecutively repeating for a long or the rest of the number.

Hope this helps!

Please help!! I have tried it on my own and I am stuck
elena55 [62]

Answer:

1. 23.59 feet

2. 32.9°

Step-by-step explanation:

1. See the diagram attached.

The man is 11 feet distance from the bottom of the tree.

And the angle of elevation from the man to the top of the tree is 65°.

Now, we need to approximate the height of the tree,

Using the trigonometry, we can write  

\tan 65^{\circ} = \frac{\textrm {Height of the Tree}}{\textrm {Base Distance}} = \frac{h}{11}

⇒ h = 11 tan 65° = 23.59 feet (Approx.) (Answer)

2. See the diagram attached.

From the given right triangle the hypotenuse is 25 feet and the base is 21 feet.

And the angle between the hypotenuse and the base is the pitch of the ram of a NASCAR turn.

Using trigonometry, we can write  

\cos \theta = \frac{\textrm {Base}}{\textrm {Hypotenuse}} = \frac{21}{25}

⇒ \theta = \cos^{-1}(\frac{21}{25}) = 32.9^{\circ} (Answer)
