Question

- Three angles of a quadrilateral are
50°78° and 84° Find the fourth angle how do this math​

Answer 1

Answer=148

Step-by-step explanation: By angle sum property sum of four angles of quadrilateral are 360 degree

so 50+78++84+x=360

=212+x=360

x=360-212=148

Answer 2

Answer:

remember the angle sum property for quadrilateral

the sum of all the angles in a quadrilateral is 360

Step-by-step explanation:

so

take the unknown angle as x

therefore,

360=50+78+84+x

360=212+x

x=360-212

x=148

the fourth angle is 148 degree
