WebIn this triangle we know the three sides: a = 8, b = 6 and c = 7. Use the Law of Cosines first to find one of the angles. It doesn't matter which one. Let's find angle A first: cos (A) = (b 2 + c 2 − a 2) / 2bc cos (A) = (6 2 + 7 2 − … WebFrom the formula above we know that the tangent of an angle is the opposite side divided by the adjacent side. The opposite side is AB and has a length of 15. The adjacent side is BC with a length of 26. This division on the calculator comes out to 0.577. So we can say "The tangent of C is 0.5776" or Example - using tangent to find a side length
