Answer:
y=3 or y-3=0
Step-by-step explanation:
-2y=-6
-2y÷(-2)=-6÷(-2)
y=-6÷(-2)
y=-6÷2
y=3
or
-2y=-6
-2y+6=0
-y+3=0
y-3=0
The distance from the lighthouse to the boat will be given by:
tan θ=opposite/adjacent
θ=angle of depression=23
opposite= height of the lighthouse
adjacent=distance from the boat to the bottom of the light house
hence
tan 23=210/a
thus solving for a we obtain:
a=210/tan23
hence
a=494.73 ft
