hyy guys


give me right answer pls


​

Answer 1

Answer: 240 m/s

Step-by-step explanation:

= 3600root3 * (root3 - 1/root3) /30

= 240

Answer 2

The angle of elevation of a jet plane from a point A on the ground is 60°. After and flight of 30 seconds, the angle of elevation changes to 30°. If the jet plane is flying at a constant height of 3600√3m, find the speed of the jet plane.

∆ABP

tan60° = BP/AB

⟾ 360√3/AB

⟾ √3 = 3600√3/AB

⟾ AB = 3600

∆ACQ

tan30° = CQ/AC

⟾ 3600√3/AC

⟾ 1/√3 = 3600√3/AC

⟾ AC = 3600 × 3

⟾ 10800

AC = AB + BC

10800 - 3600 = BC = PQ

7200 = PQ

Speed = 7200/30

$\:\:\:\:\:\:\:\:\:\:\:\:$= 240

⛬ The speed of the jet plane = 240m/sec
