There are two options here.
option 1 - base angles = 3x and non base angle = x+50.
all angles add to 180, so we get

which means two angles are: 55.714 and the last angle is: 68.57
--
option 2 - base angles = x+50 and non base angle = 3x.
all angles add to 180, so we get

which means two angles are: 66 and the last angle is: 48

How to find the third angle.
-------------------------------------------
That depends on which of the two you listed is one of the equal angles.
---
If 3x is paired with another 3x you get:
3x + 3x + x+50 = 180
7x = 130
x = 130/7
---
3x = 390/7
x+50 = (130/7) + (350/7) = 480/7
=============================================
If (x+50) is paired with another (x+50) you get:
2(x+50) + 3x = 180
5x = 80
x = 16 degrees
3x = 48
x+50 = 66 degrees.
---------------------------------------------
Comment:
Judging from those answer I would guess the x+50
is one of the two equal angles.
