Websin x = Opposite Side / Hypotenuse. cos x = Adjacent Side / Hypotenuse. tan x = Opposite Side / Adjacent Side. cot x = Adjacent Side / Opposite Side. sec x = Hypotenuse / … WebBut the value of this term is also 1. For this, please go through the trigonometric ratios of specific angles. E = tan48∘tan23∘tan42∘tan67∘ E = tan 48 ∘ tan 23 ∘ tan 42 ∘ tan 67 ∘. ⚡Tip: Pair up complementary angles. Example 4: If tan2A= cot(A−21∘) tan 2 A = cot ( A − 21 ∘), where 2A 2 A is an acute angle, find A A.
