Question

anonymous · Answer

do you know pythagoras rule? a² + b² = c² (the letters are the length of the sides). Can you solve it now?

anonymous · Answer

Do you know if the 10 is the longest side or are you solving for the longest side?

anonymous · Answer

solving the longest side

anonymous · Answer

Yes he is right use Pythagoras theorem here to find the third side. p^2+b^2=h^2
Where p is perpendicular
b is base
h is height

Using Simon's help above and a=5 and b=10 we should get:
5^2+10^2=c^2
25+100=c^2
125=c^2
c = sqrt(125) or about 11.18
