    well i know tan 45 = 1 so i guess it's 45-45-90 triangle hhmmmm

    I'm just curious what the sin/cos could be since tanB=1 and tan=sin/cos

    well for 45-45-90 two legs would have the same length |dw:1443978946557:dw| you can use Pythagorean theorem to find 3rd one

    If we have the value of one trig ratio, we can find the value of any other trig ratio :)

    so how would we set it up? I'm a little confused

    the triangle is correct! whats stopping you from finding cos B = adjacent side/ hypotenuse?

    I got 1/sqrt(2) for cos for sin 1/sqrt(2). As for the measure of b in radians I got pi/4

    \[\huge\rm rad= \frac{ \pi }{ 180 } \times \deg\] formula to convert rad to deg

    \(\large \sec^2 x = 1+ \tan^2x \) you'll get sec x \(\Large \cos x = \dfrac{1}{\sec x}\) \(\sin^2 x+ \cos^2 x =1\)

    she is fast! she already converted 45 deg to pi/4 rad
