How you get your answer is by multiplying 25*8= 125
Step-by-step explanation:
Left hand side:
tan 203° + tan 22° + tan 203° · tan 22°
From angle sum identities, we know:
tan (α + β) = (tan α + tan β) / (1 − tan α · tan β)
Therefore:
tan (203° + 22°) = (tan 203° + tan 22°) / (1 − tan 203° · tan 22°)
tan (225°) = (tan 203° + tan 22°) / (1 − tan 203° · tan 22°)
1 = (tan 203° + tan 22°) / (1 − tan 203° · tan 22°)
tan 203° + tan 22° = 1 − tan 203° · tan 22°
Substituting:
1 − tan 203° · tan 22° + tan 203° · tan 22°
