Question

If lines a and b are parallel,and measure of angle J equals x plus twenty degrees and measure of angle K equals three x, what is the value of x?

Two parallel lines, a and b, intersected by transversal, t. The angles where a and t intersect are labeled J, K, L, and M starting in the upper left and moving clockwise. The corresponding angles where b and t intersect are labeled N, P, R, and Q starting in the upper left and moving clockwise.

one hundred sixty degrees

ninety degrees

forty degrees

twenty degrees
