3 0

Easy. Do (3x + 10) + (6x -10) = 180. You add them up since they are same side interior angles. This gives you 9x = 180
Divide by 9 on both sides. x = 20. Hope this helps!

if the diameter of a circle is 15, its radius is half that or 7.5.

$\bf \textit{area of a circle}\\\\ A=\pi r^2~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=7.5 \end{cases} A=\pi (7.5)^2\implies A=56.25\pi \implies \stackrel{\pi =3.14}{A=176.625}$
