My teacher gave me the answer since I couldn't figure it out and she told me that it is 8 centimeters. And I can't figure out how to solve this question. so can someone please try to help me understand how to solve this question please??? thank you

**Ms. Sue**, Sunday, January 27, 2013 at 12:32pmWe need to use the Pythagorean Theorem.

a^2 + b^2 = c^2

a = one leg

b = one leg

c = hypotenuse

a^2 + 6^2 = 10^2

a^2 + 36 = 100

a^2 = 100 - 36

a^2 = 64

a = 8
