why is it 180?

90 degrees - this is incorrect. The three angles of any triangle always add up to 180 degrees.

The sum of the three interior angles of a triangle is always 180 degrees because of the straight line property or angle sum property. When you draw a straight line that connects the vertices of the triangle on one side (extending one side), it forms a straight line, which is a straight angle measuring 180 degrees. Since the triangle is now part of that straight line, the sum of its angles must add up to 180 degrees. This property can be proven using geometry and can be generalized for all triangles.
