What is the measure of ∠y? 43° 68° 86° 172°

Solution:

Here we are given the arc xz=86.

we have been asked to find the measure of angle Y.

As we know that the Inscribed angle is Half of the measure of the intercepted arc.

Here intercepted arc=86

So we can write

Hence the value of the angle y is 43 degrees.

The measure of is . Option (a) is correct.

Further explanation:

The angle subtended by an arc at center is double of the angle subtended by the arc at any point on the circle.

Given:

The options are as follows,

(a).

(b).
