\(\frac{11\pi}{6}\) radians is how many degrees?
B. \(330^\circ\)
\(\frac{11\pi}{6}\times\frac{180^\circ}{\pi}=330^\circ\) होता है। \(\pi\) कटने के बाद \(11\times30^\circ\) करें। / \(\frac{11\pi}{6}\times\frac{180^\circ}{\pi}=330^\circ\). After canceling \(\pi\), calculate \(11\times30^\circ\).

\(1^\circ\) is approximately equal to how many radians?
A. (0.01745) रेडियन(0.01745) radian
\(1^\circ=\frac{\pi}{180}\approx0.01745\) रेडियन होता है। छोटे डिग्री कोण का रेडियन मान छोटा होता है। / \(1^\circ=\frac{\pi}{180}\approx0.01745\) radian. A small degree angle has a small radian value.

Which angle lies in the first quadrant?
B. \(35^\circ\)
\(35^\circ\), \(0^\circ\) और \(90^\circ\) के बीच है इसलिए पहले चतुर्थांश में है। सीमा कोणों से चतुर्थांश पहचानें। / \(35^\circ\) lies between \(0^\circ\) and \(90^\circ\), so it is in the first quadrant. Identify quadrants using boundary angles.
