Answer:

(B)
{\angle}UVS=39^(\circ)

Explanation:

Given: A circle with intercepted arc is
78^(\circ).

To find: The measure of ∠UVS.

Solution:

Since, we know that the angle made of the inscribed angle is half of the intercepted arc, therefore


Inscribed angle=(1)/(2)Intercepted arc (1)

We are given that A circle with intercepted arc is
78^(\circ), thus equation (1) becomes:


{\angle}UVS=(1)/(2)arc US


{\angle}UVS=(1)/(2)(78^(\circ))


{\angle}UVS=39^(\circ)

Therefore, option B is correct.

The inside angle ( UVS) is equal to 1/2 the outside angle given.

UVS = 1/2(78)

UVS = 39 degrees

The answer is B.
