1.

Angles of a quadrilateral are respectively 120 degree 730 degree 80 degree find the fourth

Answer»

Question needs a correction,

70° is written wrong as 730°




Sum of ANGLES of QUADRILATERAL = 360°


120 + 70 + 80 + fourth Angle = 360


270 + fourth Angle = 360

Fourth Angle = 360 - 270

Fourth Angle = 90°
