Step-by-step explanation:

a=8cm

b=15cm

c=17cm

s=a+b+c/2

=8+15+17/2

=40/2

=20

Using heron's formula,

ar. of triangle= √s(s-a)(s-b)(s-c)

=√20(20-8)(20-15)(20-17)

=√20×12×5×3

=√2×2×5×2×2×3×5×3

=2×2×3×5

=60cm²

On side 17cm,

Ar. of triangle=1/2×b×h

60=1/2×17×h

∴h=60×2/17

=7.05 cm

How do you simplify this

oksian1 [2.3K]

$\frac{1-\frac{2x}{3x-4}}{x+\frac{32}{3x-4}} =\frac{\frac{3x-4-2x}{3x-4}}{\frac{x(3x-4)+32}{3x-4}} =\frac{x-4}{3x^{2}-4x+32}$

Find the circumference of a circle whose area is 24 pi ft ^2

lianna [129]

$\bf \textit{area of a circle}\\\\
A=\pi r^2~~
\begin{cases}
r=radius\\
-----\\
A=24\pi 
\end{cases}\implies 24\pi =\pi r^2\implies \cfrac{24\pi }{\pi }=r^2
\\\\\\
24=r^2\implies \boxed{\sqrt{24}=r}\\\\
-------------------------------\\\\
\textit{circumference of a circle}\\\\
C=2\pi r\qquad \qquad \implies C=2\pi\left( \boxed{\sqrt{24}} \right)~~
\begin{cases}
24=2\cdot 2\cdot 2\cdot 3\\
\qquad 2^2\cdot 6
\end{cases}
\\\\\\
C=2\pi \sqrt{2^2\cdot 6}\implies C=2\pi (2\sqrt{6})\implies C=4\sqrt{6}~\pi$
