<u>Part A</u>

<u />\overline{AC} and \overline{BD}

<u>Part B</u>

Diagonals of a parallelogram bisect each other, so

BE=ED \implies 2x+3=3y-4 \implies 3y=2x+7 \implies y=\frac{2}{3}x+\frac{7}{3}\\\\AE=EC \implies y+4=4x-6 \implies y=4x-10

Solving by substitution,

\frac{2}{3}x+\frac{7}{3}=4x-10

Multiplying both sides by 3,

2x+7=12x-30\\\\37=10x\\\\x=3.7

So, y=\frac{2}{3}\left(\frac{37}{10} \right)+\frac{7}{3}=\frac{24}{5}

<u>Part C</u>

<u />BE=ED=2(3.7)+3=10.4\\\\AE=EC=4(3.7)-6=8.8

\therefore BD=2(10.4)=20.8, AC=2(8.8)=17.6

Ksju [112]
In a linear functions, f(x)=mx+b, your y-intercept is b. So any function that is any number times x plus 3 is going to give you a y intercept of 3.

Which has a measure that is equal to the sum of the measures of the interior angles of a triangle?
Natalija [7]

The sum of the interior angles of any triangle is 180 degrees. It does not depend on which triangle we are discussing that this fact is true for all triangles. 180 degrees is a straight line.
