Thank you for asking this question. Here is your answer:
tan100° + 4sin100°
= sin100°+2sin200° / cos100°
= sin100°−2sin20° / cos100°
= 2cos60° sin40° −sin20° / cos100°
= sin40° −sin20° / cos100°
= 2cos30° sin10° / cos100°
= −√3 is the final answer.
If there is any confusion please leave a comment below.
