Mathematics
1 answer:
katrin2010 [14]2 years ago
5 0

Answer:

∠ QRS = 132°

Step-by-step explanation:

Since the triangle is isosceles then the 2 base angles are congruent, that is

∠ PQR = ∠ PRQ = \frac{180-84}{2} = \frac{96}{2} = 48°

∠ PRQ and ∠ QRS are adjacent angles , so

∠ QRS = 180° - 48° = 132°
