Answer:
Unsafe area
Step-by-step explanation:
Data provided in the question
51 m above sea level
The Safe distance from cliff = 75 m
The 10 m above ground and angle of depression of 50°
Based on the above information,
The equation is as follows
tan 50 = (51 + 10) ÷ x
where
x = distance of the boat
Now after solving this,
x = 51.2 m
Therefore we conclude that the boat is in an unsafe area
