What is the area of a right triangle with sides a, b, and the hypotenuse c ?
1.) b = 12 / a
2.) c = 5
Being that we know the hyp. is 5, and knowing the special relationship of this type of right triangle (3, 4, 5), are we able to deduce that only knowing c can give us the area?
In other words, I don't think mathematically we can get a & b w/o memorizing the 3, 4, 5 relationship of a speical right triangle the same way we would memorize 5, 12, 13. Is this info. enough to give us the area?
Would the answer to the above question be B - both answers give us the area?
Thanks,
CJ

Of course knowing 3, 4, 5 will enable us to get the area; what I meant was is this memorization an acceptable means of getting the area for this problem?
