Answer: 314
Take each number place and subtract them from each other.
<span>Let </span>
<span>X= the altitude of the lighthouse above sea
level= 80 ft</span>
A = the angle of depression
Y= the distance of the boat from the lighthouse= 400 ft
tan A=X/Y------------------ >
80/400=0.2
arctan (0.2)=11.31 degree
The answer is the angle of depression is 11 degree
Answer:
whichever one corresponds with the answers you have will be right.
