Pythagorean Theorem with Known Legs

IgorC [24]

Answer:

$\sqrt{170} = c$

Step-by-step explanation:

We are trying to find the hypotenuse of a right triangle

We will use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

11^2 + 7^2 = c^2

121 + 49 = c^2

170 = c^2

Taking the square root of each side

$\sqrt{170} = c$
