the sum of all interior angles in a polygon, is 

180(n-2).     n = number of sides in the polygon.

now, this polygon has 5 sides, a PENTAgon, therefore the sum is 180( 5 - 2) or 180(3) or 540°.

therefore then,

Q + P + T + S + R = 540


Q + 90 + 115 + 115 + 90 = 540

surely you'd know what Q is.
