Answer:
30°
Step-by-step explanation:
If we assume a right triangle, where the height is the opposite leg to the angle we are looking for and the distance from the beginning of an airstrip to the tip of the plane is the hypotenuse, we have to:
Sin ° A = Opposite leg / hypotenuse
Sin ° A = 1/2
° A = Arc Sin (1/2)
° A = 30 °
Which means that the angle that is formed is 30 °
