Solve using a system of three linear equations.A real estate investor is examining a triangular plot of land. She measures each angle of the field. The sum of the first and second angles is 112° more than the measure of the third angle. If the measure of the third angle is subtracted from the measure of the second angle, the result is thrice the measure of the first angle. Find the measure of each angle. (Note: The sum of the angles of a triangle is 180°.)
A. First angle is 32°, second angle is 120°, third angle is 28° B. First angle is 26°, second angle is 118°, third angle is 32° C. First angle is 28°, second angle is 118°, third angle is 34° D. First angle is 34°, second angle is 114°, third angle is 32°
