I have attached the diagram for this problem
We know that c and d are parallel and that 2 = 98°
By definition of vertical angles, 2 = 3 = 98°
By definition of alternate interior angles, 3 = 6 = 98°
By definition of supplementary angles, 4 = 180 - 98 = 82°
By definition of corresponding angle, 4 = 8 = 82°
By definition of alternate interior angles and vertical angles, 4 = 5 = 8 = 82°
