A right-angled trapezoid PQRS PQRS\,PQRS is shown. The vertices are labeled PPP (top-left), QQQ (bottom-left), RRR (bottom-right), and SSS (top-right). The base QR QR\,QR is horizontal and labeled 20 cm. The side PQ PQ\,PQ is vertical and labeled 8 cm. The side SR SR\,SR is vertical and labeled 13 cm. Right-angle symbols are shown at vertices Q Q\,Q and RRR, indicating that PQ⊥QR PQ \perp QR\,PQ⊥QR and SR⊥QRSR \perp QRSR⊥QR. The angle SPQ SPQ\,SPQ is the interior angle at vertex P P\,P between sides PQ PQ\,PQ and PSPSPS.
Work out the size of angle SPQSPQSPQ. Give your answer to 1 decimal place.
