Best ResponseYou've already chosen the best response.0If you need to find the length from city A to C, then you can make a triangle. Here you have the length from A to B = 200, and from B to C = 300. And the angle B would be: \[18030=150\] Now you can find the length from A to C using the law of cosines: \[c^2=a^2+b^22*a*b*\cos(B)\]
