To solve this you must use Pythagorean theorem:


a^(2) +b^(2) =c^(2)

a and b are the legs (the sides that form a perpendicular/right angle)

c is the hypotenuse (the side opposite the right angle)

In this case...

a = 8 cm

b = 6 cm

c = x

^^^Plug these numbers into the theorem


8^(2) +6^(2) =x^(2)

simplify

64 + 36 =
x^(2)

100 =
x^(2)

To remove the square from x take the square root of both sides to get you...

√100 = x

Which is when simplified:

(choice C)

10 cm

Hope this helped!
