Question

three. angles. of. a quadrilateral. are. 65. degree. and. 115 degree. and. 160. degree. find. the. fourth. angle​

Answer 1

Step-by-step explanation:

sum of all angles of quadrilateral = 360°

Let the fourth angle be = x°

therefore,

x° + 65° + 115° + 160° = 360°

x° + 340° = 360°

x° = 360° - 340°

x° = 20°

there fore , the fourth angle is 20°
