Use the drawing below as needed to answer the question. Three lines form 8 labeled angles. Line m and line n appear parallel. Line m is to the left of line n and both lines start at the bottom and go up and to the right. Line k starts to the left of both m and n and travels down and to the right intersecting m and then intersecting n. ∠1 is formed by the top side of k and the top side of m. ∠2 is formed by the bottom side of k and the top side of m. ∠3 is formed by the top side of k and the bottom side of m. ∠4 is formed by the bottom side of k and the bottom side of m. ∠5 is formed by the top side of k and the top side of n. ∠6 is formed by the bottom side of k and the top side of n. ∠7 is formed by the top side of k and the bottom side of n. ∠8 is formed by the bottom side of k and the bottom side of n. Given: m ∥ n transversal k m∠3 = (7x + y)° m∠5 = (6x + 5y)° m∠6 = (5x + 7y)° Find: x, y, and m∠7 in degrees
