Question

What is the value of $\sin 30^\circ + \cos 60^\circ$? 
 

• A. 1
• B. $\frac{1}{2}$
• C. $\frac{\sqrt{3}}{2}$
• D. $\frac{3}{2}$

Hint:

Memorize standard angles: $0^\circ, 30^\circ, 45^\circ, 60^\circ, 90^\circ$ - these make most trigonometry MCQs instantaneous.

Answer 1

The Correct Option is A

Step 1: Recall Standard Trigonometric Values

From standard trigonometric ratios:

• sin 30° = 1/2
• cos 60° = 1/2

Step 2: Add the Values

Substituting these values into the expression:

sin 30° + cos 60° = 1/2 + 1/2 = 1

Step 3: Final Answer

Therefore, the value of sin 30° + cos 60° is:
