I don't have the full diagram or which sides the 6 and 22 label. Can you clarify which sides or angle those numbers refer to (for example: AB = 6, AC = 22, BC = ?; or are 6 and 22 the legs of a right triangle)? Or upload a picture of the diagram.
Meanwhile, here are the formulas you can use:
- If you know all three side lengths a = BC, b = CA, c = AB, then use the Law of Cosines for ∠A:
cos A = (b^2 + c^2 − a^2) / (2bc).
- If the triangle is right at A and the legs meeting at A are 6 and 22, then cos A = adjacent/hypotenuse. For example, if the side adjacent to A is 6 and the other leg is 22, then the hypotenuse = sqrt(6^2 + 22^2) = sqrt(520) and
cos A = 6 / sqrt(520) ≈ 0.26 (rounded to the nearest hundredth).
Tell me which labels correspond to 6 and 22 and I’ll compute cos A exactly.
