=32x. This is the write answer
The triangle has a base of 7 so 1/2 the base is 3.5.
The height = 7.5 (from graphic)
Area of "left triangle" = 3.5*7.5 / 2 =
<span>
<span>
<span>
13.125
</span>
</span>
</span>
The entire triangle area = 2 * 13.125 =
26.25
Triangle perimeter both legs = 16.6 + base (7) = 23.6
I believe it’s the second table, (5, 25), (7, 49), (9, 81).
I think it is the ASA theorem, but im like 70% sure.
we see two angles that are being compared in additon to the joined sides of the smaller triangle inside the larger one
