a^2+b^2=c^2
So this means 9^2 + b^2= 15^2 ---> 81 + b^2 = 225
so just subtract them and you get your missing leg. 225 - 81 = 144. But not so fast. That is not the exact value of the missing leg, ITS TOO BIG. So now all you have to do is square root it. square root of 144......should equal 12 because 12 times 12 equals 144.
So there you go you found the missing leg. GOOD JOB. This missing leg is 12. BAM!!! Easy math baby! your welcome!
