Tami is looking to enclose a dog pen with a fence the pen is shaped like a quadrilateral and is modeled on the coordinate plane below. Where each unit represent a foot.

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>

he answer is x=1x3 because x=1 to x=3
