Answer:
The length of Side RT of the polygon is \(7\ units\)
Step-by-step explanation:
we know that
the formula to calculate the distance between two points is equal to
\(d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}\)
we have
\(R(-6,2)\\T(1,2)\)
substitute the values
\(d=\sqrt{(2-2)^{2}+(1+6)^{2}}\)
\(d=\sqrt{(0)^{2}+(7)^{2}}\)
\(dRT=7\ units\)
