Question 943510
A boat has to cross a river.
It crosses the river by making an angle of 60 deg with the bank of the river due to stream of the river and travels a distance of 600m to reach the another side of the river.
What is the width of the river?
:
Draw this out, see that it forms a right triangle, Side opposite the 60degree angle, is the width of the river (w), the hypotenuse is the path of the boat, 600m
:
sin(60) = {{{w/600}}}
.866*600 = w
w = 519.6 m across
