Answer 1

$\:\: \underline{\underline{\bf{\large\mathfrak\red{~~Solution~~}}}}$

as ..∆PQR≌∆XYZ..

so..∠P=∠X ; ∠Q=∠Y ; ∠R=∠Z

now..

∠P=45°=∠X

∠Y=75°=∠Q

therefore..

∠P+∠Q+∠R=180°

=>45°+75°+∠R=180°

=>∠R=180°-120°

=>∠R=60°

∴∠R=60 (answer)

Answer 2

Step-by-step explanation:

Given-ΔPQR ≅ ΔXYZ

Therefore, according to the rules of congruency,

∠P = ∠X

∠Q = ∠Y

∠R = ∠Z

∠P = 45°

∠Y = 75°

=> ∠Q = 75°

=>∠P + ∠Q + ∠R = 180°

=>45° + 75° + ∠R = 180°

=>∠R = 180°-(45° + 75°)

=>∠R = 180° - 120°

So, ∠R = 60°
