Question

Find the value of \( \sin 30^\circ + \cos 60^\circ \).

• A. 1
• B. \( \frac{\sqrt{3}}{2} \)
• C. \( \frac{1}{2} \)
• D. 0

Hint:

Remember the standard values for trigonometric functions at key angles: \( \sin 30^\circ = \frac{1}{2} \), \( \cos 60^\circ = \frac{1}{2} \).

Answer 1

The Correct Option is A

We know that: \[ \sin 30^\circ = \frac{1}{2} \quad \text{and} \quad \cos 60^\circ = \frac{1}{2} \] Now, we calculate: \[ \sin 30^\circ + \cos 60^\circ = \frac{1}{2} + \frac{1}{2} = 1 \] Thus, the value of \( \sin 30^\circ + \cos 60^\circ \) is 1. Therefore, the correct answer is option (1).
