Question on: WAEC Mathematics - 2005

In the diagram, O is the center of the circle, ∠MON = 80^o, ∠LMO = 10^o and ∠LNO = 15^o. Calculate the value of x

40^o

50^o

55^o

75^o

Ask EduPadi AI for a detailed answer

Correct Option: C

Reflex + ∠OML + ∠ONL + ∠NLM = 360
280^o + 10^o + 15^o + x = 360^o => 305^o + x^o = 360^o
x = 360^o - 305^o = 55^o
