this is the solution of the above problem

Answer 2

Answer:

any quadrilateral in world has total of 360° of measures of interior angles , so quadrilateral MANC has a total sum of interior angles as 360° , /_ANC = /_AMC (given)

So /_ ANC + /_AMC + /_MCN + /_MAN = 360°

SO

180° + /_MCN + /_MAN = 360°

SO

/_MCN + /_ MAN = 360°- 180°

THEREFORE /_MCN + /_MAN = 180°

SINCE , /_MCN : /_MAN = 2:1 (given)

Therefore 2:1 = 180°

therefore 2x + 1x = 180°

therefore 3x = 180°

therefore x = 180°/3

Therefore x = 60°

THEREFORE 2x = 60×2 = /_MCN = 120°

THEREFORE x = 60 = /_MAN = 60°
