t said Saturated liquid so the first table A-1, row with the pressure of 0.02MPa = 20kPa and col with H with small L with means liquid(KJ/Kg). And the question said the result is 80c of 5Mpa liquid water so you can find the enthalpy of it at Compressed liquid table, pretty at the bottom (A-4 Compressed Liquid). Also the table with 5Mpa and row of 80C and col of H with small L. Hope this help you :D
