दो बहुभुजों में भुजाओ की संख्याओं का अनुपात `5:4` है । यदि बहुभुजों के आंतरिक कोणो का अंतर `6^(@)` हो , तो भुजाओं की संख्या ज्ञात करे ?A. 15,12B. 5,4C. 10,8D. 20,16

Answer» Correct Answer - A
Let the no. of sides is 5x and 4x
According to the question
`(180^(@) - 360^(@)/(5x)) - (180^(@)-360^(@)/(4x)) = 6^(@)`
`180^(@)-360^(@)/(5x) - 180^(@) + 360^(@)/(4x) = 6^(@)`
`360^(@)(1/(4x)-1/(5x)) = 6^(@)`
`1/(20x) = 1/60`, x=3
No. of sides are 5x and 4x = 15,12
