Answer:

Step-by-step explanation:

You need to use a calculator.

It is however useful to remember some values for tangents.

For example tan  45 degrees = 1.

Tan 30 =  1 /√3  and tan 60 = √3.

Factor 2w+6
natta225 [31]

Answer:

2( w + 3 )

Step-by-step explanation:

Well first off, since theres no common term to factor out, I had to split 6 in half

so 2 w + 6 becomes 2w + 2 x 3.

I then factored out 2 because it's a common term,

which then leaves: 2( w + 3 )

basically, you have to find a common term to factor out, if you don't see one, you have to do something to a number so there's common terms.

Determine whether angle-angle-angle (AAA) is a valid means for establishing triangle congruence. If it is a valid criterion, exp
Igoryamba

AAA is not a valid congruence theorem. This is because we can construct two different triangles, of different shapes, and they both have the same corresponding angles. See the diagram below. Simply form any triangle you want and scale up or down to form a second triangle. The two triangles are similar, but they aren't congruent. They need to be the same size and shape to be congruent.

The entrance to the louvre museum in paris is a pyramid made of glass and steel. the height of the pyramid is 22 meters and the
In-s [12.5K]

Based on the calculations, the volume of this louvre pyramid is equal to 8,983 cubic meter..

<u>Given the following data:</u>

Base width = 35 meters.

Height = 22 meters.

<h3>How to calculate the volume of a pyramid?</h3>

Mathematically, the volume of a pyramid can be calculated by using this formula:

Volume = 1/3 × base area × height

For the base area, we have:

Area = w²

Area = 35² = 1,225 m².

Substituting the parameters into the formula, we have;

Volume = 1/3 × 1,225 × 22

Volume = 1/3 × 26,950

Volume = 8,983 cubic meter.

What function to use and how to use it
Lena [83]

That's the wrong right triangle to draw.  Reading the problem carefully we want this one, figure attached.

So we have the usual 30/60/90 triangle but not to scale.  The sides come in ratio 1:√3:2=x:100:hypotenuse.  So

x = 100/√3 ≈ 57.735

We add that to our 133.2 for the total height of the Cyclone, 190.935.

Answer: 190.9
