A. it is a hexagon (there are 6 sides) B. using the equation (n-2)180 (where n is the number of sides we get (6-2)180=4*180=720. divide 720 by 6 to get 120 for each angle of the hexagon. (it has no irregularities in it's shape so that number will be correct for them all.) C. to get that just divide 39 by 6 to get 6.5 in per side. Hope that helps:)

madreJ [45]

Answer:

ln [2^4 * 5^3]

Step-by-step explanation:

Rewrite 4 ln 2 as ln 2^4 and 3 ln 5 as ln 5^3.

Then 4 In 2+3 In 5 = ln 2^4 + ln 5^3, which in turn becomes

ln [2^4 * 5^3]

I already know the answer to this problem, I want a explanation on how to get the answer.
DochEvi [55]

\\ \bull\tt\dashrightarrow BC=CE

\\ \bull\tt\dashrightarrow 3x+3y=7x+5y

\\ \bull\tt\dashrightarrow 7x-3x=3y-5y

\\ \bull\tt\dashrightarrow 4x=-2y

\\ \bull\tt\dashrightarrow 2x=-y

\\ \bull\tt\dashrightarrow \dfrac{x}{y}=\dfrac{-1}{2}

Now

\\ \bull\tt\dashrightarrow BE=BC+CE+CD

\\ \bull\tt\dashrightarrow BE=3x+3y+7x+5y+5x-2y+6

\\ \bull\tt\dashrightarrow BE=15x+6y+6

<h2>Solution (1) :</h2>

∠<em>y</em><em> </em>and ∠<em>x</em> are alternate interior angles . Both of these angles will be equal in measure when on two parallel lines with a transversal .

<h2>Solution (2) :</h2>

∠y and ∠x are alternate interior angles . Both of these angles will have an equal angle measure when they lie on two parallel lines with a transversal .

<h2>Solution (3) :</h2>

∠y and ∠x vertically opposite angles . Both of these angles will be equal in measure when on two parallel lines with a transversal .

<h2>Solution (4) :</h2>

∠y and ∠x are adjacent angles as well as a linear pair . These angles will sum up to form 180° .
