And my points are gone

Answer 1

Answer:

The value of X in first figure is 68°.

The value of X in second figure is 106°.

Answer 2

Answer:

a) sum of all angles in quadrilateral=360°

76+135+81+x =360°

292+x=360°

x=360-292

[ x=68° ]

b) sum of all angles in quadrilateral=360°

let the angle adjacent to angle x=a

71+118+97+a=360°

286+a=360°

a=360-286

a=74°

a angles made on a line is always 180°

x+a=180°

x+74=180°

x=180-74

[ x=106° ]
