The three angles add to 180 degrees. Also , the two base angles of the isoscele triangle are equal, ..

Set those base angles equal, and solve for x.

Put that value of x into the given, and compute the base angles.

The third angle will be the amount to add to the two base angles to get 180 deg

how do I find the vertex angle of an isosceles triangle with base angles of (4x-9) and (3x+2).
