I need help with this question, so if any knows the answer lmk

Find the measure of the interior angles of the following regular polygons: a triangle, a quadrilateral, a pentagon, an octagon, a decagon, a 30-gon, a 50-gon, and a 100-gon.

The algebraic expression shown below is missing two whole number constants. determine the constants so that the expression simplified to 14x + 11 4x + 8(x + + + 2x

Determine the equivalent system for the given system of equations: 5x − 3y = 6 x + y = 2
