Question

angles of a quadrilateral are 110 degree and 78 degree and the other two angles are equal find the measure of the two unknown angles​

Answer 1

Answer:

86

Step-by-step explanation:

360-110+78

=172/2

=86

Answer 2

the first angle is 110 and the second angleis 78 degree and third angle is assumed to be x and as the two angles are equal then the fourth angle will also be x

now the sum of all angles of quadrilateral is 360 degree then,

110+78+x+x=360

110+78+2x=360

188+2x=360

2x=360-188

2x=172

x=172/2

x=86 degree

and the second will also be 86
