Use the related acute angle to state an equivalent expression:

a) tan 110 degrees
b)sin 350 degrees

4 answers

a) tan 110 degrees = tan 110-180=
tan-70
b)sin 350 degrees = sin 350-360
= sin-10 degrees
The more standard practise is to state the equivalent angle in terms of a positive acute angle.
So ...

tan 110° = -tan 70°
sin 350° = -sin 10°
The back of the book says 290 for tan110 . How is it 290 and why??.also whats equivalent to sin350 ???
ur bad
