Answer:
its 3
Step-by-step explanation:
Answer:
False
Step-by-step explanation:

SinA=8/17, so arcsin(8/17) is your angle of A (around 49 degrees). 90-A is your angle for B
We have a triangle where.
a=adjacent leg of A=30 ft
A=90º-(angle of depression)=90º-10º=80º
b=distance between the base of the lighthouse and the ship
tan A= opposite /adjacent.
tan 80º=b /30 ft ⇒b=(30 ft)(tan 80º)≈170.14 ft
Answer: the distance would be 170.14 ft
