WebThe shortest side is the one opposite the smallest angle. If the angle you already know is the shortest one, then the shortest side is opposite it. However, if the angle you already know is the medium one, then the shortest side is adjacent to it. WebThe cable makes a 39° angle with the seabed The cable has a 30 meter length. And 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.
WebAccording to Newton's second law, F = ma. Which means that Weight = mass * gravitational acceleration = m * 9.8 m/s^2. Now, you put in the mass of the object in kilograms to get the weight of the object in Newtons. … WebWe call the angle alpha then: sin (alpha) = x/r = 4/5 cos (alpha) = y/r =3/5 tan (alpha) = y/x = 4/3 Then alpha = arcsin (4/5) = arccos (3/5) = arctan (4/3) = 53.13.
