The measure of m∠14 is 110 degrees and the angle relationship is a supplementary angles
Let us assume that angle m∠10 and m∠14 are supplementary, this means that the sum of both angles will be 180 degrees.
Since the angles are supplementary, hence the required expression will be:
m∠10 + m∠14 = 180
Given that m∠10 = 70 degrees
70 + m∠14 = 180
m∠14 = 180 - 70
m∠14 = 110 degrees
Hence the measure of m∠14 is 110 degrees and the angle relationship is a supplementary angle.
