WebThe angle the cable makes with the seabed is 39°. The cable's length is 30 m. And we want to know "d" (the distance down). Start with: sin 39° = opposite/hypotenuse. Include lengths: 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. WebTo find an angle's size, use the sine rule formula where the angles are on the top. Sin (A)/a= Sin (B)/b As mentioned earlier, you only need two parts to use the sine rule, one side, and an opposite angle. Example 1 Work out angle n° in a triangle where one of the angles is 75°, and the two sides are 8 and 10cm. Solution dan rather iii
