WebSep 15, 2024 · 1.2: Trigonometric Functions of an Acute Angle. Consider a right triangle ABC, with the right angle at C and with lengths a, b, and c, as in the figure on the right. For the acute angle A, call the leg ¯ BC its opposite side, and call the leg ¯ AC its adjacent side. Recall that the hypotenuse of the triangle is the side ¯ AB. WebAnswer (1 of 3): We know that a/sin A = b/sin B = c/sin C ie. 13/sin A = 24/Sin C => 13/sin theeta = 24/sin 2theeta => 13/sin theeta = 24/2sin theeta.cos theeta => 13 = 12/cos theeta => cos theeta = 12/13 So sin theeta = √(1-cos^2 theeta)=√(1 - 144/169) = √(25/169)= 5/13 …
