Question o A propeller plane flies in 30" north of west direction with a constant speed of 400 km/h after take off. There is a strong wind of 100 km/h In 53.1" south of west direction. Find the altitude of plane (in km) 10 minutes after take off. (sin(30") = 0.50, cos(30") = 0.87, sin(53.1") = 0,80, cos(53.1") = 0.60)
