Question

Stanley has drawn a right angle triangle. One side is 14cm and another is 18cm. There are two possible lengths for the third side. What are they?

Answer 1

It could either be 22.80 or 11.31.

Answer 2

2V130 , 8V2

Explanation:

If these are cahetus

x^2=14^2+18^2=196+324=520

x=V520=2V130

if 18 is not a cathetus then

18^2=x^2+14^2

x^2=18^2-14^2

x^2=324-196=128

x=V128

x=8V2
