Question

if three angles of a quadrilateral are 65 degree 45 degree and 120 degree find the fourth angel of a quadrilateral​

Answer 1

Answer:

let angle1 = 65°

angle 2=45°

angle 3=120°

angle1+angle2+angle3+angle4=360[ angle sum property]

65+45+120+ angle 4=360°

230+angle 4=360°

angle 4= 360°-230°

=130°✔️✔️
