Answer:21
Step-by-step explanation: The median is the number in the middle sorted from least to greatest, here 21 is the middle number.
Given the graph of a line, you can determine the equation in two ways, using slope-intercept form, y=mx+b y = m x + b , or point-slope form, y−y1= m(x−x1) y − y 1 = m ( x − x 1 ) . The slope and one point on the line is all that is needed to write the equation of a line.
Answer
just reverse it. if you already have the long side plug it into the equation a2+b2=c2. and instead of adding youd subtract
