Well you can determine the unknown angle in the triangle by knowing that a triangles angles add up to 180. 64 + 52 + (Unknown) = 180 Unknown = 64 Unknown and the angle of F create a 180 angle relationship. Therefore, F = 180-64 —> 116 Angle D has a 180 angle relationship with F and so does X with D, so F and X are the same. Answer: 116
B because to be perpendicular the slope had to be opposite of the original slope but the same b. But parallel would be the exact same slope with a different b
