Answer:

  • The angles are 80° and 48°.

==============================

Let the angles be x and y.

Their ratio is 5/3:

  • x/y = 5/3

Their sum is 128:

  • x + y = 128

Solve the system by substitution:

  • x = 5y/3
  • x + y = 128

  • 5y/3 + y = 128
  • 8y/3 = 128
  • y = 3*128/8
  • y = 48

Find x:

  • x = 128 - 48 = 80
