WebWe know. The 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.

WebIt means that cos x vanishes when x is an odd multiple of π/2. So, cos x = 0 implies x = (2n + 1)π/2 , where n takes the value of any integer. For a triangle, ABC having the sides a, b, and c opposite the angles A, B, and C, the cosine law is defined. Consider for an angle C, the law of cosines is stated as. c 2 = a 2 + b 2 – 2ab cos (C) In ... WebYou could rearrange the concept a bit to get that the sum of the arguments must be 90 degrees for the sides to be equal, since the sine is the same as the cosine of the complementary angle. We can then set up an equation with just the arguments: 50 - x + 3x + 10 = 90. 2x + 60 = 90. 2x = 30. x = 15. 3 comments.
