WebJul 19, 2011 · Make sure that there is a big enough angle between these first two sides so that you can mark it. Now we have drawn the base of unknown length, the fixed angle, and the first fixed side, adjacent to the angles--the A and first S of our ASS triangle. Tape the yarn to the board at some point above the dotted line. WebAnd we want to know "d" (the distance down). Start with: sin 39° = opposite/hypotenuse sin 39° = d/30 Swap Sides: d/30 = sin 39° Use a calculator to find sin 39°: d/30 = 0.6293... Multiply both sides by 30: d = 0.6293… x 30 d = 18.88 to 2 decimal places. The depth "d" is 18.88 m Exercise
