Show that the statement is true . if DE has endpoints is D(-1,4) and E (5,-2), then the midpoint M of DE lies in Quadrant l. The midpoint M is (___,___). M lies in Quadrant , since the x-coordinate is ___, and the y-coordinate is.

Atriangle has side lengths of 15 inches and 30 inches. it also has angles that measure 45º and 20º. which of the following identifies the possible third angle of the triangle? a. 15 in., 65º b. 45 in., 65º c. 17 in., 115º d. 14 in., 115º

Solve this system of equations. 12x − 18y = 27 4x − 6y = 10

List the sides of δrst in ascending order (shortest to longest) if: m∠r =x+28°, m∠s = 2x+16°, and m∠t = x+12
