Sine Or Cosine Rule? Trigonometry Maths FuseSchool

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. WebAnalyzing Graphs of Variations of y = sin x and y = cos x.
