Putting this we get. ⇒ tan 70 ∘ − tan 50 ∘ = tan 20 ∘ + tan 50 ∘ ⇒ tan 70 ∘ = tan 20 ∘ + 2 tan 50 ∘. Hence Proved. Note: Note that we can make a general formula, which would look something like; tan θ = tan ( π 2 − θ) + 2 tan ( 2 ...

Webb3 apr. 2024 · For the same, let’s apply tan (a+b) formula and equate it to tan ( 70 0). Then, with simple simplification we’ll get the answer. Complete answer: We know that tan (a + b) = tan a + tan b 1 − tan a tan b. tan ( 70 0) = tan ( 50 0 + 20 0) So using above formulae. tan7 0 0 = tan 50 0 + tan 20 0 1 − tan 50 0 tan 20 0.
