Consider the diagram.

In the diagram, the length of segment TR can be represented by 5x – 4.

Angles X and Y are supplementary. Angle X is 3 times the measure of angle Y. What is the measure of angle X?
Consider the two planes.

2 lines connect to form a right angle. A third line extends between the 2 lines to form 2 angles which are labeled 1 and 2.

3 lines are shown. A line with points M, H, K intersects a line with points J, H, L at point H. A line extends from point H to point P between angle K H J. Angle M H L is 140 degrees and angle K H P is 20 degrees.

In the diagram, which angles form a linear pair? Select three options.





Which diagram shows lines that must be parallel lines cut by a transversal?
