Correct Answer: Option C
Explanation:
The sum of angles in a quadrilateral = 360°
\(\therefore (p + 10) + (2p - 30) + (3p + 20) + 4p = 360\)
\(10p = 360° \implies p = \frac{360}{10} = 36°\)
The sum of angles in a quadrilateral = 360°
\(\therefore (p + 10) + (2p - 30) + (3p + 20) + 4p = 360\)
\(10p = 360° \implies p = \frac{360}{10} = 36°\)
