Answer:
i think it is also 144°
Explanation:
x and o look like the same angle so it hope its 144°
x = 108°
The vertices P, Q, R, S lie on the circle, thus PQRS is a cyclic quadrilateral.
The opposite angles of a cyclic quadrilateral are supplementary, then
x + 72° = 180° ( subtract 72° from both sides )
