prove that tan60-tan30 1+tan60×tan30=tan 30please take photo . . . - Brainly Answer: Hence, the answer is =tan 30o Step-by-step explanation: Step : 1 Given: tan30 1+tan60×tan30=tan 30 1 +tan60∘ ⋅ tan30∘tan60∘ −tan30∘ = tan(60∘ −30∘) [∵ tan(A − B) = 1+ tanA ⋅ tanB tanA − tanB] = tan30∘ = 31 Hence, the answer is = tan 300 Step : 2 Tan ( 3) has a precise value of 1 3, or 1 7320508075 in decimal notation It is the inverse of a 60-degree
Prove that tan 10 tan 50 tan 70 =tan 30 - Brainly. in Answer: tan10tan50tan70 = tan30 Step-by-step explanation: We need to prove that tan10tan50tan70 = tan30 Taking LHS, LH S = tan10tan50tan70 It can be rewritten as LH S = tan 10tan(60 −10)tan(60 + 10) We know that tan(A + B) = 1 − tanAtanB tanA + tanB and tan(A − B) = 1+tanAtanBtanA−tanB Using the above formulas we get
