Question

use double-angle,power reducing,half-angle to solve.
TAN 112.5°

Answer 1

HI!!

Answer 2

\(112.5^\circ\) is half of \(225^\circ\) so you can use the half angle formula with \(225^\circ\)

Answer 3

\[\tan(11.25^\circ)=\frac{1-\cos(225^\circ)}{\sin(225^\circ)}\] would work

Answer 4

yes thank you !
