Angles 1 and 2 are supplementary.

which equation represents the relationship between their measures?

m1 + m2 = 90°
m1 + m2 = 100°
m1 + m2 = 180°
m1 + m2 = 200°

M1 + m2 = 180

complementary angles add up to 90 degrees

supplementary angles add up to 180 degrees

“exterior angles of triangles. an exterior (or external) angle is the angle between one side of a triangle and the extension of an adjacent side. try this drag the orange dots on any vertex to reshape the triangle.” look to get to the answer i explained what it means and other things i hope it you .

2160ft^3 i think you could use a formala to you out with this in the future
