PROVIDE STEPS. and 30 points.

i got x=24. I might be wrong, please don't be mad.

Step-by-step explanation:

i started with (5x-28)+(x+5)+(2x+11)=180

i combined like terms and got 8x-12=180

then i added 12 to both sides 8x=192

finally i divided by 8 on both side x=24

hopefully this is correct and helped

two data sets with the same median will not have the same varaibility

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.
