Question

Tg(55°)- tg(35)°/tg(20°)​

Answer 1

Tg (55апчи короче там это того

Answer 2

To simplify the expression, we need to use trigonometric identities. Let's break down the steps:

Step 1: Convert degrees to radians tg(55°) = tan(55°) tg(35°) = tan(35°) tg(20°) = tan(20°)

Step 2: Apply the tangent difference identity: tan(A - B) = (tan A - tan B) / (1 + tan A * tan B)

In this case, A = 55° and B = 35°, so the identity becomes: tan(55° - 35°) = (tan(55°) - tan(35°)) / (1 + tan(55°) * tan(35°))

Step 3: Calculate the values using a calculator: tan(55°) ≈ 1.4281 tan(35°) ≈ 0.7002

Step 4: Substitute the values into the formula: (tan(55°) - tan(35°)) / (1 + tan(55°) * tan(35°)) ≈ (1.4281 - 0.7002) / (1 + 1.4281 * 0.7002) ≈ 0.7279 / 2.0008 ≈ 0.3638

So, the simplified expression is approximately 0.3638.
