Example:
This suggests two solutions,
and
.
However, upon plugging these solutions back into the equation, you get
which checks out, but
does not because
is defined only for
(assuming you're looking for real solutions only). So, we call
an extraneous solution, and the complete solution set (over the real numbers) is
.
A² + b² = c²
c² = 10² + 3²
c² = 109
c = √109
c = 10.44 units (nearest hundredth)

Step-by-step explanation:
In triangle ABC, angle A is a right angle, and angle B= 45 degrees. (also AC is 12 ft). What is the length of BC? If your answer is not an integer, leave it in simplest rascal form.
