Question

Please answeeeeeeer!!!

Answer 1

Your answer is 20

As isosceles triangle has two angles similar

And sum of all angles is 180,
so

80 + 80 = 160
and
180 - 160 is
20
So ur answer is 20

Answer 2

Answer:

50°, 80° and 20° could all be possible angles

Step-by-step explanation:

Given that every triangle has three angles that must add up to 180°, there could be a few different combinations with an isosceles triangle that will add up to 180°.  

Since two angles of an isosceles triangle must be the same, then you can have the following combinations:

80° + 80° + x = 180°, or x = 20°

80° + 2x = 180°, or x = 50°

So, the possibilities out of the angles given are 80°, 20° and 50°.
