Answer 2

Given:-

• Measure of the minor arc is 120°.

To find:-

• Corresponding major arc.

Solution:-

Let,

• the minor arc be ∠AOB.

→ ∠AOB = 120°

→ ∠AOB = 2 ∠ADB

→ 120° = 2 ∠ADB

→ ∠ADB = 120/2

→ ∠ADB = 60°

Now,

• finding the corresponding major arc.

→ Reflex - ∠AOB = 2 ∠C

→ 360° - 120° = 2 ∠C

→ 240° = 2 ∠C

→ ∠C = 240/2

→ ∠C = 120°

Hence,

• the corresponding major arc is 120°.
