(90'') is equal to how many minutes?
B. \(\frac{3}{2}'\)
\(90''\div60=\frac{3}{2}'\) होता है। सेकंड से मिनट में बदलते समय (60) से भाग दें। / \(90''\div60=\frac{3}{2}'\). Divide by (60) to convert seconds into minutes.

What is the radian measure of \(225^\circ\)?
A. \(\frac{5\pi}{4}\)
\(225^\circ \times \frac{\pi}{180^\circ}=\frac{5\pi}{4}\) होता है। \(45^\circ=\frac{\pi}{4}\) याद रखने से भी उत्तर मिलता है। / \(225^\circ \times \frac{\pi}{180^\circ}=\frac{5\pi}{4}\). Remembering \(45^\circ=\frac{\pi}{4}\) also helps.

\(\frac{5\pi}{6}\) radians is equal to how many degrees?
B. \(150^\circ\)
\(\frac{5\pi}{6}\times\frac{180^\circ}{\pi}=150^\circ\) होता है। पहले \(\pi\) को काटें फिर गुणा करें। / \(\frac{5\pi}{6}\times\frac{180^\circ}{\pi}=150^\circ\). Cancel \(\pi\) first and then multiply.

\(\frac{4\pi}{3}\) radians is equal to how many degrees?
D. \(240^\circ\)
\(\frac{4\pi}{3}\times\frac{180^\circ}{\pi}=240^\circ\) होता है। \(\frac{\pi}{3}=60^\circ\) इसलिए चार गुना \(240^\circ\) है। / \(\frac{4\pi}{3}\times\frac{180^\circ}{\pi}=240^\circ\). Since \(\frac{\pi}{3}=60^\circ\), four times it is \(240^\circ\).

In which quadrant does \(210^\circ\) lie?
C. तीसरा चतुर्थांशThird quadrant
\(210^\circ\), \(180^\circ\) और \(270^\circ\) के बीच है इसलिए तीसरे चतुर्थांश में है। सीमा कोणों को याद रखें। / \(210^\circ\) lies between \(180^\circ\) and \(270^\circ\), so it is in the third quadrant. Remember the boundary angles.

In which quadrant does \(315^\circ\) lie?
D. चौथा चतुर्थांशFourth quadrant
\(315^\circ\), \(270^\circ\) और \(360^\circ\) के बीच है इसलिए चौथे चतुर्थांश में है। कोण की स्थिति सीमा से तय करें। / \(315^\circ\) lies between \(270^\circ\) and \(360^\circ\), so it is in the fourth quadrant. Decide the position using boundaries.

In which quadrant does \(100^\circ\) lie?
B. दूसरा चतुर्थांशSecond quadrant
\(100^\circ\), \(90^\circ\) और \(180^\circ\) के बीच है इसलिए दूसरे चतुर्थांश में है। \(90^\circ\) से आगे और \(180^\circ\) से पहले दूसरा चतुर्थांश होता है। / \(100^\circ\) lies between \(90^\circ\) and \(180^\circ\), so it is in the second quadrant. After \(90^\circ\) and before \(180^\circ\) is the second quadrant.
