Solving trigonometric equations
ninety divided by two is 45. So
we just plug in ninety for X and a half angle formula here
Tangent ninety over two equals one minus cosine
ninety over sine of ninety. Cosine of 90 is 0 and Sine of 90 is 1
our equation now looks a lot more welcoming and tangent of ninety divided by 2
equals one number one
so we've simplified and tangent of forty-five equals 1.
So there you go, it's answer C.
