Question

Use the related acute angle to state an equivalent expression:
a) tan 110 degrees
b)sin 350 degrees

Answer 1

a) tan 110 degrees = tan 110-180=
tan-70
b)sin 350 degrees = sin 350-360
= sin-10 degrees

Answer 2

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°

Answer 3

The back of the book says 290 for tan110 . How is it 290 and why??.also whats equivalent to sin350 ???

Answer 4

ur bad
