Answer:
Hope you got it....
Step-by-step explanation:
1=tan45∘
1=tan(22∘+23∘)
1=tan22∘+tan23∘1−tan22∘tan23∘
1−tan22∘tan23∘=tan22∘+tan23∘
1=tan22∘+tan23∘+tan22∘tan23∘
It will be the same for any two angles that add up to 45∘.
Answer:
ooo....
Step-by-step explanation:
22° + 23° = 45°
taking tan on both side
or,tan(22° + 23°)=tan45°
or,(tan22° + tan23°)/(1-tan22°. tan23°)=1
or,tan22° + tan23° =1- tan22°. tan23°
or,tan22° + tan23° + tan22°. tan23° = 1
