Answer:

true

Step-by-step explanation:

The slopes of prependicular lines have to give as a result -1 when multiplied by eachother, so for example if you have a line with a slope of 2, the perpendicular line should have a slope of -1/2 because when multiplying for one another the result will be -1. So the statement would be true, the slopes of perpendicular lines are opposite reciprocals.

An equilateral triangle has an altitude length of 36 feet. Determine the length of a side of the triangle.

liq [111]

$\bf \textit{height of an equilateral triangle}\\\\
h=\cfrac{s\sqrt{3}}{2}\quad 
\begin{cases}
s=\textit{length of a side}\\
---------\\
h=36
\end{cases}\implies 36=\cfrac{s\sqrt{3}}{2}
\\\\\\
72=s\sqrt{3}\implies \cfrac{72}{\sqrt{3}}=s~~\stackrel{rationalizing~it}{\implies }~~\cfrac{72}{\sqrt{3}}\cdot \cfrac{\sqrt{3}}{\sqrt{3}}\implies \cfrac{7\sqrt{3}}{3}$
