Question

The hypotenuse of a right triangle is 15 cm, and the shorter leg is 9 cm. Find the length of the other leg.

Answer 1

I believe the answer is 135 degrees

Answer 2

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!
