Find the missing length of the triangle.

Answer:
12 in.
Step-by-step explanation:
Leg = a = 9 in.
Leg = b
Hypotenuse (side opposite of the right angle) = c = 15 in.
Use the pythagorean theorem to find the missing side length
[tex]a^2 + b ^2 = c ^2[/tex]
[tex]9^2 + b^2 = 15^2[/tex]
Simplify
[tex]81 + b^2 = 225[/tex]
Subtract 81 from both sides of the equation
[tex]b^2 = 144[/tex]
Find the square root of 144
b = [tex]\sqrt{144}[/tex]
b = 12
12 in
