Question

20. A rocket flies 10 kmı vertically, then 20 km at an angle of 15° to the vertical and finally 60 km at an angle of 26 degrees to the vertical. Calculate the vertical height of the rocket at the end of the third stage.​

Answer 1

Step-by-step explanation:

h = 10 + 20 cos(15°) + 60 cos(26°) = 83.246 km
