Question : If $\sin 3x=\cos(3x-45^{\circ}), 0^{\circ}<3x<90^{\circ}$, then $x$ is equal to:
Option 1: $45^\circ$
Option 2: $22.5^\circ$
Option 3: $35^\circ$
Option 4: $27.5^\circ$
Correct Answer: $22.5^\circ$
Solution : Given: $\sin 3x = \cos(3x - 45^\circ)$ We know that, $\sin \theta = \cos(90^\circ - \theta)$ ⇒ $\sin 3x = \sin(90^\circ - (3x- 45^\circ))$ ⇒ $3x = 90^\circ - 3x+45^\circ$ ⇒ $6x = 135^\circ$ ⇒ $x = 22.5^\circ$ Hence, the correct answer is $22.5^\circ$.
Question : Jeevan can do a piece of work alone in 42 days, while Rishi and Jeevan together can do the same piece of work in 27 days. How many days will Rishi take to complete the same piece of work alone?
