Use the following isosceles triangle to find valur of x and the length of ac.

marissa [1.9K]

Given that the triangle is isosceles, we can say that AB = AC. Using the given expressions we can form the following equation.

$\begin{gathered} AB=AC \\ 5x+8=7x-6 \end{gathered}$

Let's solve for x.

$\begin{gathered} 8+6=7x-5x \\ 14=2x \\ x=\frac{14}{2} \\ x=7 \end{gathered}$

Once we have the value of the variable, we can find the length of AC.

$\begin{gathered} AC=7x-6 \\ AC=7(7)-6 \\ AC=49-6 \\ AC=43 \end{gathered}$ <h2>Therefore, the length of AC is 43.</h2>

deff fn [24]

Ameena will need a total of 7 packages of paper. (Not every sheet will be used, but having just 6 packages won’t give here enough paper to use). Here’s why:

If she needs 74 copies of the newsletter, and each newsletter contains 8 pages, then she will need a total of 592 pieces of paper (74*8=592). 7 packages will give her 630 pieces of paper to use (90*7=630). 6 packages would only give her 540 pieces of paper (90*6=540), so she needs 7 total packages of paper.
