Question

three angles of a quadrilateral are 77°, 95°and 83° find the fourth angle​

Answer 1

Answer:

105° is the right answer

Answer 2

Step-by-step explanation:

let 4th angle be x

we know that the sum of the angles of quadrilateral is 360°

77° + 95° + 83° + x = 360°

245° + x = 360°

x = 360° - 245°

x = 115°

hence 4th angle is 115° ( Ans )
