If the degree ratio of the top and bottom angles of an isosceles triangle is 2:1, what are the top and bottom angles of the triangle

If the degree ratio of the top and bottom angles of an isosceles triangle is 2:1, what are the top and bottom angles of the triangle

Vertex angle 180x2 / (2 + 1 + 1) = 180x2 / 4 = 90 (degrees)
Bottom angle 180x1 / (2 + 1 + 1) = 180x1 / 4 = 45 (degrees)
