Answer:
80
Step-by-step explanation:
An isosceles has 2 angles that are the same so 50+50 is 100 so we have 80 degrees left to make a full triangle because all angles will always add up to 180 so 50+50+80 is 180 degrees
50 and/or eighty because it’s an isosceles and that makes it two of the angles the same so the the other has to be fifty and the interior sum of a triangle is 180 always and fifty plus fifty is a hundred so you need eighty to finish it off
