Explanation:
step 1
Find the measure of angle ISV
we know that
-----> by supplementary angles
we have
substitute


step 2
Find the measure of arc PK
we know that
The measure of the inner angle is the semi-sum of the arcs comprising it and its opposite
Let
x-----> the measure of arc IV
y-----> the measure of arc PK

substitute the values and solve for y
