prove that tan45 =1
vijaykarthikeyan35:
In triangle abc,
Angle A= 90
Angle b = 45 ( given )
Angle c = 45 ( angle sum property)
Therefore ab = bc
Tan 45 = bc/ab
=1
= RHS

Tan ø =sinø/cosø so,
tan 45°=sin45°/cos45°
➡tan45°=1/root 2 upon 1/root 2
By cancelling the value we will get,
Tan45°=1
Hope it helps you mark as brainliest dear ❤❤✌
