30 in the diagram line e and made parallel to each other and line p and q are transversal. use properties of special angles formed by parallel lines and their transversals to find the missing angle measures. m< 3=65 m< 15=120 m< 7= m< 4= m< 6= m< 1= m< 16= m< 18= m< 21= m< 10= m< 11= m< 12=

2y= 3 2 x−2 y = − 1 3 x + 1 y=− 3 1 x+1

What is the value of x in the following equation. -x ^3/2 = -27
