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. WebIf we consider the right angle, the side opposite is also the hypotenuse. So sin (90)=h/h=1. By pythagorean theorem, we get that sin^2 (90)+cos^2 (90)=1. So, substituting, 1+cos^2 (90)=1 cos^2 (90)=0 cos (90)=0 And we see that tan (90)=sin (90)/cos (90)=1/0. … cinnamon roll pound cake grandbabyWebThere can be two since sin (theta) = sin (180-theta) for all values of theta that are real numbers e.g. -1000.98, sqrt (2) etc. Since you are using the sin^-1 function you will only ever get 1 angle as the range is defined from -90 to 90 degrees (which is -pi/2 to pi/2 in radians).
