Hi !! please help me solve this !!
2. Ship A is at a distance of 3km from the lighthouse, whereas ship B is 4 km away. If the lines of sight from the lighthouse to the two ship form an angle of 60 degrees, then how far are the two ships from each other


Sagot :

Answer:

thus, the distance between ship A and B is 3.6km

Step-by-step explanation:

a=?
b=3km
c=4km
A=60°
a²=b²+c²-2abcosA
a=√3²+4²-2(3)(4)cos(60°)
