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.© BrainMass Inc. brainmass.com December 15, 2022, 6:44 pm ad1c9bdddf
