Given : cos A = 0.6; find all other trigonometrical ratios for angle A.

Question

KnowledgeBoat · Accepted Answer

Given: cos A = 0.6 cos cos i.e. ∴ If length of AB = 3x unit, length of AC = 5x unit. In Δ ABC, ⇒ AC2 = AB2 \+ BC2 (∵ AC is hypotenuse) ⇒ (5x)2 = (3x)2 \+ BC2 ⇒ 25x2 = 9x2 \+ BC2 ⇒ BC2 = 25x2 \- 9x2 ⇒ BC2 = 16x2 ⇒ BC = ⇒ BC = 4x sin tan cot cosec sec Hence, sin , tan , cot , cosec and sec .
