sarah was thinking of a number. sarah subtracts 20 from it and gets and answer 16.7. What was the original number?

b is the answer that makes most sense

step-by-step explanation:

but there’s no any figure there!

the equation is not included but the answer is (1.50, 2.00, 2.75)

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.
