Answer:
The boat is 5727.25ft far from the coast
Step-by-step explanation:
Refer the figure given.
We need to find how far is the boat from the coast = AB
Angle of elevation = 2°
The lighthouse on the coast is 200 feet tall, AC = 200 ft
We have

The boat is 5727.25ft far from the coast
If we were to foil
after experieence
we know
ax²+bx+c=0
and
in form
(ax+b)(cx+d)=0
if we expand it, we get
acx²+bcx+adx+bd=0
or
(ac)x²+(bc+ad)x+(bd)=0
compare to
ax²+bx+c=0
we notice that the middle terms (x terms) are
b=(bc+ad)
so
in form
(2x-1)(1x+5)
b=bc+ad=(-1*1+2*5)=-1+10=9
b=9
or you could just expand it
