To find the size of angle PXR, we can use the angle addition postulate which states that the sum of two adjacent angles is equal to the measure of the combined angle.
Given that PQR = 80 and SRT = 20, we know that angles PQR and SRT are adjacent angles that share a common ray, QR.
Therefore, we can find the size of angle PXR by adding the measures of angles PQR and SRT:
PXR = PQR + SRT
PXR = 80 + 20
PXR = 100
So, the size of angle PXR is 100 degrees.
