Answer 2

Answer:

i) 95 ii)

Step-by-step explanation:

i) we know 3 angles

1st: 120

2nd: 55

3rd: let the exterior angle be x => 90+x = 180 => x = 180-90 => x = 90

4th: as it is unknown let it be y

as per angle sum property in quadrilaterals

1st + 2nd + 3rd + 4th = 360°

120°+55°+90°+y = 360°

265°+y = 360°

y = 360°-265°

y = 95°

ii) given: ABCD is a quadrilateral, exterior angle B = 80°,

interior angle B = 180-80 = 100°,

interior angle D = 100°(vertically opposite angles)

Find: exterior angle D

interior angle D + exterior angle D = 180°

100°+exterior angle D = 180°

exterior angle D = 180° - 100°

exterior angle D = 80°
