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°.
