Question

Find the length of side A on a triangle where side B is 4 and side C (the hypotenuse) is 5.

Answer 1

Answer:

Your answer is: C) 3

Step-by-step explanation:

The formula used to find side A in this problem is called the Pythagorean Theorum.  The formula is as follows:  a = the square root of c squared minus b squared.  Or, you can say that the hypotenuse is equal to: c = the square root of a squared and b squared  added together.  This might sound confusing in the start, but here's all you have to do. c^2 = 25.  4^2 = 16.  25 - 16 = 9.  The square root of 9 = 3.  C) 3 is your answer.
