Remember:

The sum of the measures of the interior angles of a triangle is 180°.

a + b + c = 180

The measure of the exterior angle of a triangle is equal to the sum of the measures of the two remote interior angles of the triangle.

a + b = d

Yes, you need the word degrees or the degree symbol for answers that are angle measures.
