use the patterns to find the values of sin 30° and cos 30° and then compare their values
sin 30° = cos 30°
sin 30 ° = -cos 30°
sin 30° > cos 30°
sin 30° < cos 30°
sin 30° = 1/2
cos 30° = √3/2
Comparing their values:
sin 30° = cos 30° is false, as sin 30° is 1/2 and cos 30° is √3/2.
sin 30° = -cos 30° is also false, as sin 30° is positive (1/2) and cos 30° is negative (√3/2).
sin 30° > cos 30° is also false, as sin 30° (1/2) is less than cos 30° (√3/2).
Therefore, the correct statement is sin 30° < cos 30°.
