Angle Relationships Parallel Lines and Triangles

Using the picture of the parallel lines cut by the transversal, identify whether the following pairs of angles are "congruent" or "supplementary": Angle 3 and Angle 5

• Congruent

• Supplementary

Line T is parallel to Line V. Find the m\angle3 if the m\angle5 =119\degree

Which equation could be used to find the value of x in the triangle.
