How do I know that l -32 l is greater or less than l 15 l

When it is in between the two rods like that, it is a positive. So, in other words, these two numbers are:

32 and 15

What is more? 35, of course.

35>15

That is how! Hope I helped ya!

boxplot e is the answer

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
