In the diagram, the measure of z1 is 55°. if line y is rotated 5° clockwise about the point of intersection, what is the new measure of z3? 50° 130° 60° 120° me

It says in the questions that it is 6.5?

At a constant it will take one hour to travel 32 mi.at that speed it will take 1/2 hr to travel the remaining 16 mi.it will take 1+1/2 hr to travel the 48mi @ 32mph.so 1 hr = 60 min& 1/2 hr = 30 min1+1/2 hr = 90 min.there are 60s in each 90 × 60 = 3600 seconds.the real question seriously is he why are they driving so slow? ! lol.

Ithink the versus years?
