Answer 1

step by step explain

flight is just a flying at a speed of 648 km per hour = 648000/3600 m/s = 180 m/s %3D Distance covered in 10 secs = 180 * 10 = 1800 %3D m Height at which flying = H m H/Tan30 - H/Tan60 = 1800 => HV3 - H/V3 = 1800 => 3H - H = 1800v3 => 2H = 1800V3 =>H = 900v3 = 1,558.8 m the constant height at which the Jets flying = %3D 900v3 = 1,558.8 m Learn more: The angle of elevation of top of a pole from two points A and B on ... https://brainly.in/question/11520026 if the angle of elevation of the sun is 60° then the ratio of the height...
