Well area of a triangle is
$\frac{1}{2} b \times h$
so,
$36 \times 2 = 72 \\ 72 \div 9 = 8$
The answer is 8

Answer & Step-by-step explanation:

This can be proven with the SAS theorem (side-angle-side)

With a perpendicular bisector, the line it bisects is cut directly in half. This creates two equal sides:

$GJ=IJ$

and it creates two 90° angles:

∠ $GJH=$ ∠ $IJH$

And because of the reflexive property of congruence:

$JH=JH$

Side-Angle-Side.
