True or False: Given the illustration below, the value of y is 100º

we are given
we know that
sum of all angles in any quadrilateral is 360
so, we can write it as
[tex] y+120+85+53=360 [/tex]
now, we can combine it
[tex] y+258=360 [/tex]
now, we can subtract both sides 258
[tex] y+258-258=360-258 [/tex]
[tex] y=102 [/tex]
so, this is FALSE..........Answer
