Answer» -Exterior Angle of Triangle = 120°Interior Opposite ANGLES = 4:2To FIND :-Angles of the Triangle .Solution :-Let the interior opposite angles be 4X and 2x .As we know that , the sum of the interior opposite angles is EQUAL to exterior angle.Now :4x + 2x = 1206x = 120x = 120/6So , The value of x is 20 ..THEREFORE , The two interior opposite angles are 80 and 40 .. |
