Answer:

Base Angles Theorem Converse

Please mark the brainliest

Step-by-step explanation:

Sum of angles in a triangle is 180°

So 50°+80°+x=180°

x=180-50-80

x=50°

There are two congruent angles of 50° here so according to the base angles theorem converse, the opposite sides are congruent as well making the triangle isosceles.

Answer 2

Answer:

then the third side length is also 80 or 50 degree
