tan 2a có ứng dụng trong việc nghiên cứu về môi trường không?

Mar 26, 2025 ... We have tan 2A = cot (46° - A) ⇒ cot (90° - 2A) = cot (46° - A), ⇒ (90° - 2A) = (46° - A), ⇒ A = 44° ∴ The measurement Sep 1, 2021 ... Comparing the angles we get, 90° – 2A = A – 18° ⇒ 3A = 108° ⇒ A = 36° Therefore, the value of A is 36°.
