1. Find the area of the following triangle: c = 210 ft, A = 42.5 degrees, B = 71.4 degrees
All I know is C will be 66.1 degrees...

a. a neat way to get area is this relation
area=sqrt(s(s-a)(s-b)(s-c))
where s is half the perimeter, and a,b,c are the sides.
You can get the last side with the law of sines.
area=sqrt(s(s-a)(s-b)(s-c))
where s is half the perimeter, and a,b,c are the sides.
You can get the last side with the law of sines.
b. false. Consider this sequence:
-3,-2,-1, 0, 1, 2, ...
-3,-2,-1, 0, 1, 2, ...
