We know, by angle sum property, the sum of angles of a quadrilateral is 360
o
.
Given, one angle is 108
o
and remaining three angles are equal.
Let the remaining angles be x
o
,y
o
,z
o
.
Since they are equal, x
o
+y
o
+z
o
= x
o
+x
o
+x

=3x
o
.
Then, 108
o
+x
o
+y
o
+z
o
=360
o
⇒ 108
o
+3x
o
=360
o
⇒ 360
o
−108
o
=3x
∘
⇒ 252
o
=3x
∘
⇒ x
o
=

252
o
=84
∘
.
Therefore, each of the three remaining angle is x
o
=84
o
.
