157 degrees ... set 4x-5 = x+16 then solve, you should get x=7, plug in 7 for one of the equations and you'll get 23. subtract 23 from 180 and get 157. hope that helped :)
After the translation the vertices would be
p(6,5)
q(11,3)
r(3,11)
I think its 71. I'm not completely sure because from what ive learned it would be that.
