Sagot :
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
X=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
