Ответ:
If the right triangle is not sitting
on its hypotenuse, then one leg
is the base, and the other leg is
the height: A = (1/2) (base leg) (height leg) .
If the triangle is isosceles, then
the legs are equal: A = (1/2) (either leg)²
You said the area is 18 in²: 18 in² = (1/2) (leg²)
Multiply each side by 2 : 36 in² = leg²
Square root each side: 6 in = leg
