WebWell, the opposite side, we already figured out, has length 12. And the adjacent side, we already figure out, has length 5. So the tangent of A, which is opposite over adjacent, is 12/5. Now, we'll go the to the other three trig ratios, which you could think of as the reciprocals of these right over here. But I'll define it. WebIn a right triangle, the cosecant of an angle is the length of the hypotenuse divided by the length of the opposite side. In a formula, it is abbreviated to just 'csc'. Of the six possible … Reciprocal of a number. The reciprocal of a number is one over that number. So for …

WebJan 2, 2024 · We should also note that with the labeling of the right triangle shown in Figure 3.2.4, we can use the Pythagorean Theorem and the fact that the sum of the angles of a triangle is 180 degrees to conclude that a2 + b2 = c2 and α + β + γ = 180 ∘ γ = 90 ∘ α + β = 90 ∘. Example 3.2.1. WebThe sides of a 45°, 45°, 90° triangle, which can also be described as a π 4, π 4, π 2 triangle, have lengths in the relation s, s, 2 s. These relations are shown in Figure 8. Figure 8 Side lengths of special triangles. We can then use the ratios of the side lengths to evaluate trigonometric functions of special angles. WebIn a right triangle, the two variable angles are always less than 90° (See Interior angles of a triangle). But we can in fact find the secant of any angle, no matter how large, and also the secant of negative angles. For more on this see Functions of large and negative angles.
