PLS ANSWER ASAP!!, What is the measure of angle 6, if lines x and y are parallel, and 7 measures 121°?

A.122°
B.69°
C.59°
D.49°

59°

Step-by-step explanation:

as angle 6 and 7 are co interior angle

121°+ x°=180°

x=180-121

x=59°

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.
