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

It is known that \( \sin 30^\circ = \frac{1}{2} \) and \( \cos 60^\circ = \frac{1}{2} \). The sum is calculated as follows: \( \sin 30^\circ + \cos 60^\circ = \frac{1}{2} + \frac{1}{2} = 1 \). Consequently, \( \sin 30^\circ + \cos 60^\circ \) equals 1. This corresponds to option (1).
