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. WebThe cosine of an angle is the x coordinate of a point on the unit circle (circle with center at (0, 0), radius 1) when rotated from the positive x axis through the given angle. So draw a unit circle and find the point on the circle on the positive x-axis. Since the angle is 0, we’re not rotating at all. What is the x coordinate of that point?
