Answer 2

Answer:

In ΔABC: a = 20°, b = 130° and c = 50°

In ΔPQR: a = 65°, b = 115° and c = 25°

Step-by-step explanation:

1) In ΔABC

∠A = 30° + 60° = 90°

∠C = 70°

∴ a = ∠B = 180° - ∠A - ∠C = 180° - 90° - 70° = 20°

b = 180° - a - 30° = 180° - 20° - 30° = 130°

c = 180° - b = 180° - 130° = 50°

In ΔPQR

a = 180° - 60° - 55° = 65°

b = 180° - a = 180° - 65° = 115°

c = 180° - b - 40° = 180° - 115° - 40° = 25°
