Shields · Answer 1

The problem has two solutions

1. If 9 and 12 are legs, then the hypotenuse (x) is:

x = √ (9²+12²) = √ (81+144) = √225 = 15

2. If 9 is the leg, and 12 is the hypotenuse, then the other leg (x) is:

x = √ (12²-9²) = √ (144-81) = √63 ≈ 7.94

Demarcus Kirk · Answer 2

A^2 + b^2 = c^2 for right triangle

2 possible cases: a=9, b=12

c^2 = 9^2 + 12^2 = 81 + 144 = 225

c = 15

or a=9, c=12

b^2 = 12^2 - 9^2 = 144 - 81 = 63

b = 7.94
