Answer:
SUPER SIMPLE =
if r//s then the two angles which in this case are 110 and 80 should be equal but clearly in this case are not so the the lines r and s arent parallel to each other .
One way to do this is use the fact that the exterior angles of all polygons add up to 360 degrees
So an exterior angle of a regular octagon = 360 / 8 = 45 degrees.
So each interior angle = 180 - 45 = 135 degrees
so total measure of all angles in octagon = 8 * 135 = 1080 degrees
5+9=14 in numerical expression
may i please get brainlyest She can make 42 identical packages which contains 2 chocolate chip cookies and 1 sugar cookies.
