Answer:If the vertex angle is x, then the base angle is 2x.  Since the base angles of an isosceles triangle are equal, the other base angle is 2x.

The sum of the angles of a triangle are 180 so:  x + 2x + 2x = 180 and x = 36 and 2x = 72.

Thus, the vertex angle is 36 degrees and the two base angles are 72 degrees each.

Most likely, just multiply the numbers on the ratio by 2 or if you want to go lower, multiply by 1/2
