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 80° 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°.)

Question

A. First angle is 24°, second angle is 112°, third angle is 44°
B. First angle is 26°, second angle is 106°, third angle is 48°
C. First angle is 18°, second angle is 110°, third angle is 48°
D. First angle is 20°, second angle is 110°, third angle is 50°

Answer 1

Answer: D
