I really dont understand this question. Please show steps.
1) angle(NEA) = ½·( arc(NA) - arc(TA) ) = ........
2) angle(ENA) = ½·arc(TA) = ........
3) angle(EAN) = 180o - angle(NEA) - angle(ENA) = .......
4) angle(NAS) = 180o - angle(EAN) = ........
Tysm
what's the question here???
calculate angle NAS
