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}

In triangle QRS QT=5 and TS=22 what is RT? Explain!!
Anton [14]

Answer:

\large\boxed{RT=\sqrt{110}\approx10.49}

Step-by-step explanation:

ΔTQR and ΔTRS are similar (AA). Therefore the sides are in proportion:

\dfrac{RT}{QT}=\dfrac{TS}{RT}

We have QT = 5m ans TS = 22m. Substitute:

\dfrac{RT}{5}=\dfrac{22}{RT}          <em>cross multiply</em>

RT^2=(5)(22)

RT^2=110\to RT=\sqrt{110}
