Question

Three yachts are anchored on the harbor.
How far is Yacht 2 from the harbor?

Answer 1

is yatch 1also the same angle as where the harbor is ?

Answer 2

let the angle at yacht 1 be x
and y be the distance between yacht 2 and the harbour

tanx = y/100

angle (2 harbour 3) = 90-(180-90-x) = x
distance between 2 and 3 = 181-100=81

tanx = 81/y

y/100 = 81/y
y^2 =8100
y=90 or -90(rej)
