Help please,
1)a painter needs to cover a triangular region 63 meters by 69 meters by 71 meters. a can of can cover 70 square meters.. how many cans will be needed?
( Is this 29 cans?)
2) Find the missing part of the triangle. C= 116.1 degrees, a= 7.8 m, b= 8.2m
( Is this c= 13.6, B=33 degrees, A= 30.9 degrees, I'm bad at these ones and I think I'm wrong?)

2) is also correct, though I get A = 31.1, but this may be just a rounding off error.
