Questions & Step-by-Step Solutions
If sin A = 1/2, what is the value of A in degrees?
Steps
Concepts
Step 1: Understand that sin A = 1/2 means we are looking for an angle A where the sine value is 1/2.
Step 2: Recall the basic sine values for common angles. The sine of 30 degrees is known to be 1/2.
Step 3: Therefore, we can conclude that A = 30 degrees.
Trigonometric Functions
– Understanding the sine function and its values for specific angles.
Angle Measurement
– Converting between radians and degrees, and recognizing common angle values.
