Answer:
The value of angle of elevation is 44.4° .
Step-by-step explanation:
Given as :
The measure of the rope of hot air balloon = 100 m
The height of balloon above the ground = 70 m
Let The angle of elevation = Ф
Now, According to question
Sin angle =
Or, SinФ =
Or, SinФ =
Or, SinФ =
∴ Ф = ()
I.e Ф = 44.4°
Hence The value of angle of elevation is 44.4° . Answer
Answer is A
