For this case we have the following angle:
 theta = (9/5) pi
 Having the conversion we have:
 theta = ((9/5) pi) * (180 / pi)
 Rewriting we have:
 theta = (9/5) * (180)
 theta = (9/5) * (180)
 theta = 324 degrees
 Answer:
 
The angle is equivalent to:
 
theta = 324 degrees

How to solve this equation
mariarad [96]
\bf \sqrt{5x+19}-4=3x-15
\\\\
\sqrt{5x+19}=3x-15+4\\\\ \sqrt{5x+19}=3x-11\leftarrow \textit{square both sides}
\\\\
(\sqrt{5x+19})^2=(3x-11)^2
\\\\
5x+19=(3x-11)^2\qquad 
\begin{cases}
(3x-11)^2\to (3x-11)(3x-11)\\
 --------------\\
\textit{or use FOIL to expand it}
\end{cases}

then solve for "x"

Ok so I’m thinking that s = 93 because first I multiply first sides of the equation by -4, which was s-61=32. Then I moved the constant to the right hand side and change its sign which will be s=32+61. After I did all of that I added the numbers together and got 93..... therefore s=93
