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=

Given the two similar triangles, how do i find the missing length? if a=4, b=5, and b'=7.5 find a'

Rewrite so the subject can be y in the formula d=m-y/y+n
