Question

if the angle of a quadrilateral is 75 ° 110°and 35° find the measure of fourth angle​

Answer 1

Answer:

Let the forth angle be x

total sum of angles in  quadrilateral is 360°

75 ° + 110° + 35° + x = 360°

220° + x = 360°

so , x = 360° - 220°

          = 140°

Hence  measure of fourth angle​ is 140 °

Answer 2

140°

Answer:

degree of a quadilateral = 360°

degree of a quadilateral = 360°acc to the The given condition,

75° + 110° + 35° + x° = 360°

x = 360 - 75 - 110 - 35

x = 140°
