Answer:

Step-by-step explanation:

∠PQY + ∠RQY = 180   {STRAIGHT LINE}

∠PQY + 118 = 180

∠PQY = 180 - 118

∠PQY = 62

PY = QY

Therefore, ∠QPY = ∠PQY    {angles opposite to equal sides are equal}

∠QPY = 62

PR // XZ & YP is transversal

∠XYP = ∠QPY    {Alternate interior angles are equal}

a = 62°
