Question

one angle of an isosceles triangle is 100 degree find the measure of remaining two angle​

Answer 1

Answer:

100 + x + y = 180

x = y ( Isosceles property)

100 + 2x = 180

2x = 80

x  40

So, y = 40

The other to angles are 40 degrees!

Answer 2

Answer:

And hence the opposite angles to those sides will also be equal. The sum of angle of a triangle is 180. The other two angles are 40 each.
