Answer» InΔ QTR∠ TQR +∠ QRT +∠ QTR = 180°⇒ 40° + y + 90° = 180°⇒ y = 180° - 130°⇒ y = 50°∠ QSP =∠ SPR +∠ SRPReason : Exterior angle = sum of interior angles⇒ x = 30° + y⇒ x = 30° + 50°⇒ x = 80°So, ∠x= 80° and∠ y = 50° Tq

Answer»

InΔ QTR∠ TQR +∠ QRT +∠ QTR = 180°⇒ 40° + y + 90° = 180°⇒ y = 180° - 130°⇒ y = 50°∠ QSP =∠ SPR +∠ SRPReason : Exterior angle = sum of interior angles⇒ x = 30° + y⇒ x = 30° + 50°⇒ x = 80°So, ∠x= 80° and∠ y = 50°
