Question

the angles of a quadrilateral are 100 degrees 80 degrees and 110 degrees find the fourth angle​

Answer 1

Answer:

Step-by-step explanation:

Sum of angles of quadrilateral = 360 degree

Let the fourth angle be x

100 degree + 80 degree + 110degree+X = 360

290 degree + X = 360

Hence, X = 70 degree

Answer 2

Angle 1 + Angle 2 + Angle 3 + Angle 4 = 360°

100 + 80 + 110 + Angle 4 = 360

Angle 4 = 360 - 290

Angle 4 = 70
