Answer:
70 degree, 30 degree
Explanation:
We are given that [tex]\theta[/tex] is in standard position.
The reference angle [tex]\theta[/tex] is the acute angle.
Acute angle :The angle is always less than 90 degree.
The reference angle formed by terminal side of angle [tex]\theta[/tex] with x-axis.
When [tex]\theta=110^{\circ}[/tex]
Then, the reference angle =[tex]\bar{\theta}=180-110[/tex]
[tex]\bar{\theta}=70^{\circ}[/tex]
When [tex]\theta=210^{\circ}[/tex]
Therefore, the reference angle
[tex]\bar{\theta}=210-180[/tex]
[tex]\bar{\theta}=30^{\circ}[/tex]
