by SAS. Yes

Step-by-step explanation:

∠HIG and ∠JIK are vertical angles, so:

m∠HIG = m∠JIK

$\dfrac{GI}{IJ}=\dfrac{7.5}3=2.5\\\\\dfrac{HI}{IK}=\dfrac{2.5}1=2.5$

$\left\{\dfrac{GI}{IJ}=\dfrac{HI}{IK}\quad\ \wedge\quad m\angle HIG=m\angle JIK\right\}\implies \triangle HIG\sim\triangle JIK\ \ by\ SAS$

Step-by-step explanation:

$\frac{a}{A}=\frac{\theta }{360^o}\\ \\ a=\frac{\pi r^2 \theta}{360^o}\\ \\ a=\frac{\pi (8.7)^2(126^o)}{360^o}\\ \\ a=\frac{9536.94\pi}{360}in^2\\ \\ a\approx 83.23 in^2$
