Question : 58 of 100

Marks: +1, -0

Points

A, D, C, B

and

E

are concyclic. If

\angle A E C=50^{\circ}

and

\angle A B D=30^{\circ}

, then what is the measure (in degrees) of

\angle C B D

Solution:

Given,

∠ A E C=50^{∘}, ∠ A B D=30^{∘}

We know that,

∠ A E C=∠ A B C=50^{∘}

⇒ \;\; 50^{∘}=∠ A B D+∠ D B C

⇒ \;\; 50^{∘}=30^{∘}+∠ C B D

∴ \;\; ∠ C B D=20^{∘}
