You have to find the GCF of 140 and 180.
The GCF is 20 so thats your answer.
One of the missing angles is 45degrees 64+71=135 then subtract from 180 since it is a triangle. Then 64 are vertical angles with the one across from it which stays the same. The last angle would be 64+56=120 and 180-120=60 which would be the last angle. Hope this Helps... Juan
- The thing that is different about each of the 20 amino acids is the make-up of the R group.
This answer would be a cuboid because it has parallel,perpendicular,and diagonal cross sections
