Two planes start from los angeles international airport and fly in opposite directions. the second plane starts 1/2 hour after the first plane, but its speed is 60 kilometers per hour faster. find the airspeed of each plane if 2 hours after the first plane departs, the planes are 3135 kilometers apart.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

n
