Question
Find the degree measure corresponding to the following radian measure (Use `pi = 22/7`)
-4
Solution
- 4
`22/7` radian = 180°
- 4 radian = `180/22xx7xx (-4)` degrees
= - `2520/11` degree
= `- 229 1/11` degree
= - 229° `(1/11xx60)`
= - 229° 5`(5/11xx60)`
= - 229° 5' 27" (nearest)

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
