So base on your question that ask to find the other measurements of the angles that is formed by 2 straight length of wire where as the measurement of one angle is 72 degrees. The wires has a pair of adjacent angles and each of them has 180 degree in total, so the measurement is 108,72,108
see the attached picture to better understand the problem
we know that <span>Vertical angles are congruent </span> <span> and
adjacent angles are supplementary </span> <span> if the measure of one of the angles is </span> degrees and straight lines equal <span> degrees you have to subtract </span> from so
The easiest way to do this is for you to subtract all the sides from the total perimeter since the perimeter is all of the sides added and your remainder is your answer
