Question

if three angles of a quadrilateral are 55,33,80, find fourth angle


​

Answer 1

Angles of a quadrilateral sum up to 360 degree .

so,

    x+55+33+80=360

    x=360-55-33-80

    x=192

Answer 2

Answer:

192° is your answer my friend.

Step-by-step explanation:

let the quadrilateral be ABCD

let A = 55°

let B = 33°

let C = 80°

let D = y

as we know that sum of all angles of a quadrilateral = 360°

A + B + C + D = 360°

55° + 33° + 80° + y = 360°

168° + y = 360°

y = 360° - 168°

y = 192°
