Answer:
The other side = units
Step-by-step explanation:
A right triangle has a side of length units and;
the hypotenuse is
According to Pythagorean theorem,
a² + b² = c² , where a and b are the two legs of a triangle and c is the hypotenuse.
Lets say a² = and c² = (
b² = c² - a²
b² = -
=
So b = =
units.
So the other side = units.
