two planes, a and start from the same place and move in different directions, making an angle of 50° between them the speed of plane ais
200 miles per hour, and the speed of plane b is 300 miles per hour
the two planes are
miles apart after one hour

0

Step-by-step explanation:

because plane A speed is 200mph and at 50°; plane B speed is 300 mph and it is at less than plane A i.e 50°

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°
