In a circle of radius 60 inches, a central angle of 35° will intersect the circle forming an arc of length

Dmitriy789 [7]

$\bf \textit{arc's length}\\\\
s=\cfrac{\theta \pi r}{180}~~
\begin{cases}
r=radius\\
\theta =angle~in\\
\qquad degrees\\
------\\
r=60\\
\theta =35
\end{cases}\implies s=\cfrac{(35)(\pi )(60)}{180}\implies s=\cfrac{35\pi }{3}$

pav-90 [236]

The total area of the the picture and frame is given by the equation A = (16 + 2x)(24 + 2x) = 384 + 32x + 48x + 4x^2 = 4x^2 + 80x^2 + 384

What is the value of x?

adell [148]

again, we're assuming that both triangles are similar, and thus using proportions.

$\stackrel{\textit{assuming the triangles are similar}}{\cfrac{x+1}{27}=\cfrac{5}{x-5}\implies x^2+x-5x-5=135}\implies x^2-4x-5=135 \\\\\\ x^2-4x-140=0\implies (x-14)(x+10)=0\implies x = \begin{cases} 14~\textit{\large \checkmark}\\ -10 \end{cases}$

we do not use the -10, because whatever value "x" may be, can't be negative or even 0.
