WebMar 1, 2024 · Explanation: We know from the given that cos(θ) = 3 5 So then to simplify further, we will divide: cos(θ) = 3 5 → cos(θ) = 0.6. Since we want to find the value of θ, we have to use the inverse operation on the calculator. We want to figure out which angle (that has the value of θ in this example) resulted in a cosine of 0.6. WebGoogle Classroom. Learn how to find the sine, cosine, and tangent of angles in right triangles. The ratios of the sides of a right triangle are called trigonometric ratios. Three common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan). These are defined for acute angle A A below: ecclesiastes verse about left and right
