angle A and angle B are supplementary angles. If m angle A=(7x+7)^ and m angle B=(4x-14)^ then find the measure of angle B .

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.
