WebMay 1, 2024 · We need to use the trig identity that cos(2A) = cos²A - sin²A, where A is an angle. In this case, A is ∠ABC. Essentially, we want to find cos∠ABC and sin∠ABC to solve this problem. Cosine is adjacent ÷ hypotenuse. Here, the adjacent side of ∠ABC is side BC, which is 4 units. The hypotenuse is 2√5. So, cos∠ABC = 4/2√5 = 2/√5.

Solution: Since sin x = (3/5) we have cosec x = 1/sin x = (5/3) Now sin 2 x + cos 2 x = 1. i.e., cos 2 x = 1 – sin 2 x. or cos 2 x = 1 – (3/5) = 1 – (9/25) = (16/25) Hence cos x = ±(4/5) Since x lies in second quadrant, cos x is negative.
