Answer 1

Answer:

Angle AOB = 110degree = Angle DOC (Vertically opposite angle)

With angle sum property,

Angle AOD = Angle BOC = 70degree

Also, OA = OB = OC = OD

Hence, Triangle AOD is an isosceles triangle, with angle sum property,

AOD + ODA + DAO = 180

70 + x + x = 180

2x = 110

X = 55degree = ODA

Similarly, in triangle OCD,

OCD + CDO + DOC = 180degree

110 + y + y = 180

2y = 70

Y = 35 degree

Answer 2

Answer:

A suspension is a heterogeneous mixture in which the solute particles do not dissolve, but get suspended throughout the bulk of the solvent, left floating around freely in the medium. ... This distinguishes a suspension from a colloid, in which the suspended particles are smaller and do not settle.
