Answer:
140° and 50°
Step-by-step explanation:
The supplement of the angle (180 - x)
The complement of the angle = (90 - x)
 (180 -x) = 4(90-x) - 60
180 - x = 360 -4x - 60
180 -x  = 300 - 4x
 180 - x + 4x = 300
  180 + 3x = 300
      3x = 120
       x = 40
     
The supplement (180 - x) =  180 - 40 = 140°
The complement (90 - x) =  90 - 40 = 50°
