Question
Which of the following is correct?
[Hint: 1 radian = `180^circ/pi = 57^circ30^'` approx]
Options
sin1° > sin1
sin1° < sin1
sin1° = sin1
sin1° = `pi/180^circ sin1`

Solution
sin1° < sin1
Explanation:
We know that if θ increases then the value of sin θ also increases
So sin1° < sin1 .....`[because 1 "radian" = pi/180 sin1]`

Let the angles of the quadrilateral be \[\left( a - 3d \right)^\circ, \left( a - d \right)^\circ, \left( a + d \right)^\circ \text{ and }\left( a + 3d \right)^\circ\]
We know: \[a - 3d + a - d + a + d + a - 2d = 360\]
\[ \Rightarrow 4a = 360\]
\[ \Rightarrow a = 90\]
We have:
Greatest angle = 120°
Now,
\[a + 3d = 120\]
\[ \Rightarrow 90 + 3d = 120\]
\[ \Rightarrow 3d = 30\]
\[ \Rightarrow d = 10\]
Hence,
\[\left( a - 3d \right)^\circ, \left( a - d \right)^\circ, \left( a + d \right)^\circ\text{ and }\left( a + 3d \right)^\circ\] are
