WebNow, we can use the definition of tangent to find the value of tan A: tan A = sin A / cos A tan A = (-4/5) / (-3/5) tan A = 4/3. Therefore, the exact value of tan A is 4/3, so the answer is (A) 4/3. Answer 14 : Correct answer is : b. 8.2 m he depth of the water at any time t is given by the formula: h = 2.5sin[2pi * (t - 4)/12.4] + 1.6 WebThe hypotenuse will be the larger value (√2) and the other two sides will both be 1. This makes sense, especially when we plug these values into the Pythagorean theorem: a^2 + b^2 = c^2 1^2 + 1^2 = (√2)^2 1 + 1 = 2 2 = 2 So now we have our sides, so we can very easily find sin/cos/tan values. sin = O/H = 1/√2 cos = A/H = 1/√2 tan = O/A = 1/1 = 1 photon use teh prefab offline https://redwagonbaby.com
