HELPPPPPP PLZZZZ!!!

a=15, b=15, c=???
what is the exact value of c? type an exact answer using radicals as needed.

Question

anonymous · Answer

use a^2 + b^2 = c^2

anonymous · Answer

15 ^2 = 225
225 +225 = 450
c^2 = 450
c = \[\sqrt{450}\

anonymous · Answer

Using Pythagorean's Theorem, find c.
$$a^{2}+b^{2}=c^{2}$$
$$15^{2}+15^{2}=c^{2}$$
$$450=c^{2}$$
$$\sqrt{450}=c$$
