$$a ^{2}+b ^{2}=c ^{2}$$

radar · Answer

Use the pythagorean formula which states the sum of each side squared is equal to the square of the hypotenuse.  Do you know which side is the hypotenuse?

anonymous · Answer

no i dont :( nidnt know how to solve it

radar · Answer

The longest side is the hypotenuse, it is also the side that is opposite the right (90 degree) angle.

In your triangle it is the one that is given a measure of $$\sqrt{18}$$

Do you want to solve this problem?

anonymous · Answer

okay !

radar · Answer

What is the hypotenuse squared?  In other words what is:$$\sqrt{18}\sqrt{18}$$

radar · Answer

Next square the side that is given (3).  that is what is 3*3 ?  That would be 9.

radar · Answer

Waiting for the $$\sqrt{18}\sqrt{18}= ????$$

radar · Answer

$$\sqrt{18-9}=\sqrt{9}=3$$ A A A A A
