Answer:

  55°

Step-by-step explanation:

Let x represent the measure of the smaller angle. Then the larger angle is ...

  3x -50

and the sum of the angles is ...

  x + (3x -50) = 90

  4x = 140 . . . . . . . . . add 50 and simplify

  x = 35 . . . . . . divide by 4 -- the smaller angle

  90 -35 = 55 . . . . the larger angle

The larger angle measures 55°.
