Each small square on the grid is 1 ft². Which estimate best describes the area of this figure? 25 ft² 35 ft² 50 ft² 65 ft² A 9-sided irregular polygon graphed on a coordinate plane. Some vertices of the polygon do not lie on the intersections of the grid. The region inside the polygon is shaded blue. There are 34 whole unit squares that are shaded. Approximately 20 unit squares are partially shaded.

the anwser is d) 75°

step-by-step explanation:

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
