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
Move both constants to the right than change the sign
4b=-9-3
then calculate -9-3 which is -12
now we have 4b=-12
now we isolate 4 by dividing both sides of the equation
4b= -12
which is
b= -3
so no
