Answer:

Arc VU = 44°

Explanation:

Given:

Arc SV means ∠SOV = 120°

Arc VU means ∠VOU = ?

We know that, from central angle theorem, central angle made by arc is twice the angle made the same arc at the circumference.

∴ ∠SOU = 2 × ∠STU

⇒ ∠SOU = 2(82°)

⇒ ∠SOU = 164°

Now, from angle addition theorem,

∠SOU = ∠SOV + ∠VOU

⇒ 164° = 120° + ∠VOU

⇒ 164° - 120° = ∠VOU

⇒ ∠VOU = 44°

Therefore, the measure of the arc VU is 44°.
