Answer 1

Answer:

Answer:

∠CBE is 60°.

Step-by-step explanation:

Given :

ABCD is a cyclic quadrilateral.

∠ADC is 120°.

To find :

Measure of angle ∠CBE.

Solution :

Cyclic quadrilateral are those quadrilateral whose all vertices of quadrilateral lies of circumference of circle.

We know,

✿ Sum of opposite sides of the cyclic quadrilateral are equal to 180°.

So,

\leadsto⇝ ∠CBA + ∠ADC = 180°

\leadsto⇝ ∠CBA + 120° = 180°

\leadsto⇝ ∠CBA = 180° - 120°

\leadsto⇝ ∠CBA = 60°

Now,

We also know,

✿ Sum of all angles forms on straight line is equal to 180° we can say linear pair.

So,

\leadsto⇝ ∠CBA + ∠CBE = 180°

\leadsto⇝ 60° + ∠CBE = 180°

\leadsto⇝ ∠CBE = 180° - 60°

\leadsto⇝ ∠CBE = 120°

Thus,

Measure of ∠CBE is 120°.
