the measures of the interior angles of a triangle are x,y and 2x respectively. if the triangle is isosceles, what is one possible measure of an angle of this triangle, in degrees?

if x and y are the equal angles,
then
x+y+2x = 180
x+x+2x=180
x = 45
angles: 45, 45, 90
if the x and 2x are the equal angles
then
x + y + 2x = 180
x+2x+2x=180
x = 36
angles:
36, 72, 72
