"Find the value of each variable and the measure of each labeled angle." I have
two lines crossing like an X. The left is (3x + 8), the bottom is (5x + 4y), and the
right is (5x - 20). And just so ... If I subtracted it, then I would get 8x or 10x = 180 -
4y. ... since those 2 angles are equal, then each one must be equal to 1...
