speed east = 20 sin 30 - 12 sin 80
speed north = 20 cos 30 -12 cos 80
so
speed east = -1.82
speed north = 15.2
Tan Angle from north = -1.82 /15.2
so angle = -6.83
compass direction clockwise from north = 360 -6.83 = 353
speed = distance/hour
= sqrt(1.82^2+15.2^2) = 15.3 km/hour Hope this helps Please give me brainlist
