Cos theta 60 degrees
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 ( 7 votes) Upvote Downvote Flag more WebThree common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan). These are defined for acute angle A A below: In these definitions, the terms opposite, adjacent, and hypotenuse refer to the lengths of the sides. SOH-CAH-TOA: an easy way to …

Webtheta - 90 = - (90 - theta) This version of the formula gives the same answer. The reason is because cosine is an "even" function. It has symmetry about 0. Even means: cos (theta) = cos (-theta) cos (+45deg) = 0.707 = cos (-45deg) cos (90 - theta) = cos (theta - 90) = sin (theta) Whew, I thought you had me there for a second.
