Answer:

The answer is 3,240

Step-by-step explanation:

In geometry, an icosagon or 20-gon is a twenty-sided polygon. The sum of any icosagon's interior angles is 3240 degrees.

In mathematics, the interior angles of a polygon are the angles on the inside of the polygon created where the sides of the polygon meet. When a polygon is a n-sided regular polygon, meaning it has n sides, its sides have the same length, and its angles have the same measure, we have that the measure of one interior angle is given by the formula $180 -\frac{360}{n}$

A ladder is placed against the side of a house. The top of the ladder is 12 feet above the ground. The base of the ladder is 5 f

This is the Pythagorean theorem where the 2 legs of a triangle squared add up to equal the squared hypotenuse (a^2 + b^2 = c^2)

The equation would be
12^2 + 5^2 = x^2

144 + 25 = 169

The square root of 169 = 13

Answer - 13 ft

What is the exact value of cos 45° ?

Georgia [21]

Let the two sides of a right triangle be equal to one, which means that the hypotenuse is √2

Since cosa=adjacent side / hypotenuse

cos45=1/√2

We can rationalize the denominator by multiplying numerator and denominator by √2

√(2)/2

or if you prefer: √(1/2)

Please help me What is the mode of the data shown in this stem-and-leaf plot?

monitta

<h3>Answer: 24</h3>

Explanation:

The mode corresponds directly to the most frequent leaf, ie the leaf that shows up the most. This is because the mode itself is the most frequent value of a list of numbers. Be sure to keep the rows separate. The leaf "5" shows up twice, but it's for two different stems. The leaf "7" is a similar story.

In row two, we have the leaf "4" show up three times which is the most of any leaf for any given stem. Tie that leaf to the stem 2 and we get the value 24.

The mode is 24.

Write a quadratic equation in factored form to model the given problem. Be sure to write the entire equation.

MAXImum [283]

Base= x
Height= 4+x

Area = (1/2)(x)(4+x) = 6

Hence, quadratic equation is,

(x)(8+2x) = 12
