Alice spins the spinner 3 times. what is the probability that she spins an a, then a b, and then a c?
a. 1/3
b. 1/9
c. 1/27
d. 1/12

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.

hi there, i would be interested to you with your test, may you add the questions and answer options.
