Solution
The correct option is D
144 degrees
144 डिग्री Let the Angles be x,2x,3x and 4x respectively. According to the question, x+2x+3x+4x = 360 Thus, x = 36 degrees Now, the largest angle = 4x = 144 degrees
माना कोण क्रमशः x, 2x, 3x और 4x हैं। प्रश्न के अनुसार, x + 2x + 3x + 4x = 360 इस प्रकार, x = 36 डिग्री अब, सबसे बड़ा कोण = 4x = 144 डिग्री
