Hi dear your answer is given .
Ques= tan22°+tan23°+tan22°+tan23°
ans= tan(90°- 22°)+tan(90°- 23°)+tan22°+tan23°
= cot22°+cot23°+tan22°+tan23°
= cot(22°+23°)+tan(22°+23°)
= cot55°+tan55°. (ans)
it will help
Ques= tan22°+tan23°+tan22°+tan23°
ans= tan(90°- 22°)+tan(90°- 23°)+tan22°+tan23°
= cot22°+cot23°+tan22°+tan23°
= cot(22°+23°)+tan(22°+23°)
= cot55°+tan55°. (ans)
it will help
