If sin θ = and θ is an acute angle, find the values of cos θ and tan θ.

Question

KnowledgeBoat · Accepted Answer

sin θ = Let perpendicular = 3x and hypotenuse = 5x By using Pythagoras theorem, we get : Hypotenuse2 = Base2 + Perpendicular2 Base2 = Hypotenuse2 - Perpendicular2 Base2 = (5x)2 - (3x)2 Base2 = 25x2 - 9x2 Base2 = 16x2 Base = 4x cos θ = tan θ =
