suppose S is between R and T. Use the Segment addition Postulate to solve for each variable when: RS= 2z+6 St= 4z-3 Rt=5z+12

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.

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.

(hint): the answer is in the question.
