Question

(iii) tan 105° from the functions of 45° and 60°​

Answer 1

$\tt{ \underline{Question :}}$

→ Tan 105° from the functions of 45° and 60°_??

$\tt{ \underline{Answer :}}$

→ -2 tan 45° - tan 60°

$\tt{ \underline{Explanation :}}$

→ Because

→ Tan 105 = -2-13

→ We know that tan 45° = 1

→ Tan 60° = √3

→ Tan 105 = -2-√13

→ -Tan 45 - Tan 45 -Tan 60

→ -1-1-13

→ -2-13

→ Hence ,

→ Tan 105 can be written as -tan 45° - tan 60°__!!
