I’ve tried the other answers in this app but non of it works help

Answer and Step-by-step explanation:

The lines are parallel, so that means that some angles are congruent to each other.

On the other side of 80 degrees, it would be 100 degrees (180 - 80 = 100).

Using the interior angles theorem, this means that the angle in the triangle and 50 added up are equal to 100. So, the angle C is equal to 50.

Now, because of the triangle angles sum theorem, the angles have to add up to 180, so we do 180 - 80 - 50, which is 50 (for angle A).

So, since the two angles have 50 degrees, the triangle is an isosceles triangle.

Hope this helps! (That is the explanation btw)
