Plane 1 is 176.27 miles away, and plane 2 is 222.34 miles away. The angle formed with the tracking station is 38.59*. What is the distance between the planes? Please help! :)
we know that Applying the law of cosines c²=a²+b²-2*a*b*cos C in this problem a=176.27 miles b=222.34 miles C=38.59° c=the distance between the planes so c²=176.27²+222.34²-2*176.27*222.34*cos 38.59°----> c²=19239.15 c=138.71 miles
