Answer:

a. 15 inches

Step-by-step explanation:

Pythagorean theorem:

a² + b² = c²

a² = 9in

b² = 12in

9² + 12² = c²

9² = 81

12² = 144

81 + 144 = 225

c² = 225

simplify = √225

√225 = 15

We know this because we can use the Pythagorean theorem to answer the question.

a^2+b^2=c^

12^2 +9^2=c^

225=c^2

And the answer we get is 15
