Question

The hypotenuse of a right triangle is 13 cm long .If one of the remaining two sides is of length 5 cm ,find the length of the other side.

Answer 1

Pythagoras theorem states,
${hypotenuse}^{2} = {base}^{2} + {height}^{2}$
Substitute the given values and you'll get,
(13)^2 = base ^2 + (5)^2
169 = base ^2 + 25
Square root of (169- 25) = base
Square root of 144 = base
Base = 12 cm.
