One of the adjacent angles of a parallelogram is 50° less than other. The measure of greatest angle is ________

Question

Remi · Answer

Answer:   115°    Step-by-step explanation:   The adjacent angles of a parallelogram are supplementary.   Let the smaller angle be x.  Greater angle = (x+50)°  => x+x+50 = 180°  => 2x = 180° - 50°  => 2x = 130°  => x = 130 ÷ 2  => x = 65  Therefore, greater angle = (65+50)° = 115°
