19) 300-ft lighthouse trig: 2 boats, 18* and 62* angles of depression; find dist betw

[happiness]

Problem 19) How I got 631: I did 300/sin 18 - 300/sin 62. Are the boats 631 ft apart from each other? If I am wrong, what did I do wrong?

You used the wrong trig function.

Can you explain why you used sine?
