This would be 30 because you have to add all the numbers you get from the problem so it would look like this ---> (19 +27 +25+21+44+22+45+34)8 = 29.625=30 (multiply the 8 with everything else just incase if you dont know how i got 29.625=30)
Hope this helps a lot :)
and a brainliest would help a lot

Answer:

270°

Step-by-step explanation:

(0, -1) is at the 270° angle. If you do a 360°, you end up back where you started, so the angle is still 270°.

Step-by-step explanation:

Points A(-3, -3), B(-2, 2), C(3, 3), and D(2, -2) are the vertices of a quadrilateral.

Find lengths of the sides as distances between points:

$AB=\sqrt{(-2-(-3))^2+(2-(-3))^2}=\sqrt{1^2+5^2}=\sqrt{26}\ units\\ \\BC=\sqrt{(3-(-2))^2+(3-2)^2}=\sqrt{5^2+1^2}=\sqrt{26}\ units\\ \\CD=\sqrt{(2-3)^2+(-2-3)^2}=\sqrt{1^2+5^2}=\sqrt{26}\ units\\ \\AD=\sqrt{(2-(-3))^2+(-2-(-3))^2}=\sqrt{5^2+1^2}=\sqrt{26}\ units$
