Question

KnowledgeBoat · Accepted Answer

Let us draw a right angle triangle ABC. We know that, sin A = Substituting values we get, Let BC = 3k and AC = 4k. In right angle triangle ABC, By pythagoras theorem, ⇒ AC² = AB² + BC² ⇒ (4k)² = AB² + (3k)² ⇒ AB² = 16k² - 9k² ⇒ AB² = 7k² ⇒ AB = We know that, cos A = . tan A = . Hence, .
