Answer:
130º 160º
Step-by-step explanation:
a triangle has total interior angles of 360º
An Isosceles triangle has 1 different and 2 same angles
if one angle is 100º then you have 260º left for 2 angles
If the different angle is 100º then the other two same angles add up to 260º
That would mean that both same angles are 130º (260/2)
If the 100 is one of the same angles that means one other angle is 100
100 x 2 = 200 360 - 200 = 160º.
that would make the different angle 160º
