WebTo derive b), divide line (1) by x2; to derive c), divide by y2. Or, we can derive both b) and c) from a) by dividing it first by cos 2θ and then by sin 2θ. On dividing line 2) by cos 2θ, we have. 1 + tan 2θ = sec 2θ. 1 + cot 2θ = csc 2θ. The three Pythagorean identities are thus equivalent to one another. Proof 2. WebSo all we need to do is-- well we can simplify the left-hand side right over here. 65 plus 90 is 155. So angle W plus 155 degrees is equal to 180 degrees. And then we get angle W-- if we subtract 155 from both sides-- angle W is equal to 25 degrees. And we are done solving the right triangle shown below.
