Answer :
Answer:
∠ PRQ = 48°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the two opposite interior angles.
∠ QPN is an exterior angle of the triangle , then
∠ PRQ + ∠ PQR = ∠ QPN ( substitute values )
∠ PRQ + 55° = 103° ( subtract 55° from both sides )
∠ PRQ = 48°
