    ok we know angle A equals angle C since 90-45=45 |dw:1436475407394:dw|

    |dw:1436475460289:dw| I chose to let them both be 1 and by Pythagorean theorem the hyp is sqrt(2)

    so we can also consider other angles too?

    C is 45 deg tan(45)=opp/adj =1/1=1 so yes 1 is difference from 1/sqrt(2)

    and if you can consider other angles then so does sec(C) and csc(C)

    tan(C) and tan(A) and sec(A) and csc(A) and sec(C) and csc(C) will all work

    you can also so sin(B) and cos(B) and tan(B) and csc(B) and sec(B) and cot(B) can also work too
