A stream is flowing at 0.75ms\(^{-1}\) and a boat heading perpendicular for the stream landed at the opposite bank at an angle of 30°. Calculate the velocity of the boat.

0.75/v = cos 30
V = 0.75 × 0.866
V = 0.6495
V= 0.65
Ans: D

opp/hyp = sin 30°
0.75/hyp = 0.5
hyp = 0.75/0.5
hyp = 1.50 = A

Shouldn't it be Sine instead of cos?

there's no correct option in the question. the velocity everyone is calculating is the one relative to the strem. the velocity of the boat is perpendicular to that of the stream.

why is it cos, 0.75 is the opposite, not adjacent.
