Angles and Systems of Equations
Two angles are supplementary of each other. Twice one angle is equal to the other angle minus the product of six and eight.
A. Set up a system of linear equations to represent the two angles. (Hint: You will need two equations and two unknowns.)
B. Graph each of the equations on one rectangular coordinate system. (Hint: You must get y by itself before graphing.) Scale the graph accordingly; you will need your x-axis and y-axis to go to at least 200.
C. What do you notice about the intersection of the two lines?
D. Solve the system of equations in part A to determine the degrees of each angle by using Gaussian elimination.
