a) Write the expressions for the heights of stool Y and Z.

b) If twice the height of stool Z is equal to the sum of the height of stool X and Z, can you solve for the
height of stool X? Explain why or why not.

can somebody please help


my answer got deleted but it's a

step-by-step explanation:

don't report but were is the digram

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.

60: 45 =12: 9 =4: 3 so the answer is 4: 3
