Come on girl, take a guess. This one you got.

anonymous · Answer

@Cosmichaotic  It's 220

imstuck · Answer

The angles PQR and PSR are congruent because this is a quadrilateral.  So the value of its arc is twice the measure of the angle, which is 70.

imstuck · Answer

Now what do you think?

imstuck · Answer

An inscribed angle's arc is twice the measure of the angle.

anonymous · Answer

arc PSR = 2 mutiplied by 70 = 140 

arc PQR =    360 - 140= 220 !

imstuck · Answer

No, you don't have to do that subtraction.

imstuck · Answer

Oh...oops. I made a boo-boo, I think!

imstuck · Answer

220 is right, dear girl!  I was thinking of parallelograms, not quadrilaterals!  My bad!  Good job!
