Sagot :

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°
