Question

a right angle triangle has one length 5m and one 10m what is the length of the 3rd side?

Answer 1

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

Answer 2

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

Answer 3

solving the longest side

Answer 4

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

Answer 5

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
