1.	InΔPQR,if ∠P−∠Q=42∘ and ∠Q−∠R=21∘,find ∠P,∠Q and∠R.
Answer» $I n Δ P Q R, i f ∠ P - ∠ Q = 42^{\circ} a n d ∠ Q - ∠ R = 21^{\circ}, f i n d ∠ P, ∠ Q a n d ∠ R .$

InΔPQR,if ∠P−∠Q=42∘ and ∠Q−∠R=21∘,find ∠P,∠Q and∠R.

Answer»

$I n Δ P Q R, i f ∠ P - ∠ Q = 42^{\circ} a n d ∠ Q - ∠ R = 21^{\circ}, f i n d ∠ P, ∠ Q a n d ∠ R .$
