The display of a student's calculator shows: 1.2731568 The student is most likely looking at

A rational number

Step-by-step explanation:

A rational number refers to numbers which can be expressed as the quotient or fraction of two integers, a numerator and a denominator.

Example: x/y

Where,

x= Numerator

y= Denominator

The denominator must not be 0

That is, y can not be zero (0)

Rational numbers includes: 1/2, 4/3, 3/9, but not 7/0

Therefore,

1.2731568 is the result of dividing rational numbers

step-by-step explanation:

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.
