The answer to your question lies on the Pythagorean theorem.
+c%5E2+=+b%5E2+%2B+a%5E2+
But, if you are finding for a, the solution would be:
+%28c%5E2+-+b%5E2%29+=+%28%28b%5E2+%2B+a%5E2%29+-+b%5E2%29+
then...
+c%5E2+-+b%5E2+=+a%5E2+
then...
+sqrt%28+c%5E2+-+b%5E2+%29+=+a+
Use this formula. Here are the step by step version:
+sqrt%28+c%5E2+-+b%5E2+%29+=+a+
+sqrt%28+40%5E2+-+9%5E2+%29+=+a+
+sqrt%28+1600+-+81+%29+=+a+
+sqrt%28+1519+%29+=+a+
Thus, the equation will produce an answer of approximately 39. So that I could be more precise, 38.97435053981015345483629909243.
