Answer 2

Answer:

Angle x = 60°

Angle y = 60°

Step-by-step explanation:

As we know that, diagonals of a Rhombus bisect each other at 90°.

Therefore,

Angle DOC = Angle COB = Angle BOA = Angle

AOD = 90°

→ We know that , in a triangle sum of all interior angles is equal to 180°

=> In ∆ AOB,

angle OAB + angle AOB + angle OBA = 180°

30° + 90° + x = 180°

120° + x = 180°

x = 180° - 120°

x = 60°

→ Similarly,

=> In ∆ AOD,

angle A + angle O + angle y = 180°

30° + 90° + y = 180°

120° + y = 180°

y = 180° - 120°

y = 60°

Therefore,

Angle x = 60° = Angle y
