WebAnswer: For right angle triangle ABC, sinθ =Perpendicular/ Hypotenuse=4/5 cosθ =Base/ Hypotenuse=3/5 tanθ =Perpendicular/Base= 4/3 Question 2: What are the 3 trigonometric ratios? Answer: The 3 trigonometric ratios are sine, cosine and tangent. We can find out the sine (or cosine or tangent) of either of the known- 90° angles. WebSin of 90 degrees is one. Cos of 90 degrees is 0, because if the angle has rotated through 90 degrees, there is nothing left of the adjacent side. ... sin-1, cos-1 & tan-1 are the inverse, NOT the reciprocal. That means sin-1 or inverse sine is the angle θ for which sinθ is a particular value. For example, sin30 = 1/2. sin-1 (1/2) = 30. ... cedh texto cedh slp
