WebThe exact value of sin 90 degrees is equal to 1. What is the value of hypotenuse of sin 90 is 1 and opposite side is equal to 5 units? By the formula of sine function, we know, Sin (angle) = Opposite side/Hypotenuse Sin 90 = 5/Hypotenuse 1 = 5/H Hypotenuse = 5/1 Hypotenuse = 5. How do we write sin 90 degrees in radians? 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.
