Problem

Find four angles in different quadrants with the reference angle $15^{\circ}$. Enter your answers for $0^{\circ} \leq \theta \leq 360^{\circ}$ in increasing order.

Solution

Step 1 :Define the reference angle as \(15^{\circ}\).

Step 2 :In the first quadrant, the angle is just the reference angle itself, which is \(15^{\circ}\).

Step 3 :In the second quadrant, the angle is \(180^{\circ} - 15^{\circ} = 165^{\circ}\).

Step 4 :In the third quadrant, the angle is \(180^{\circ} + 15^{\circ} = 195^{\circ}\).

Step 5 :In the fourth quadrant, the angle is \(360^{\circ} - 15^{\circ} = 345^{\circ}\).

Step 6 :Final Answer: The four angles in different quadrants with the reference angle \(15^{\circ}\) are \(\boxed{15^{\circ}, 165^{\circ}, 195^{\circ}, 345^{\circ}}\).
