Answer:

A

Step-by-step explanation:

Using the pythagorean theorem, a^{2} +b^{2} =c^{2}

we plug the numbers in; 3^{2} + 6^{2} =c^{2}

9+36=c^2

45=c^2

sqr root of 45 is \sqrt{45}

next find the positive perfect sqr root of 45 which will be 9.

9 goes into 45 5 times so it will be \sqrt{9x5}

Sqr root of 9 is 3 so it will be 3 \sqrt{5}
