Question

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

Answer 1

we are given

we know that

sum of all angles in any quadrilateral is 360

so, we can write it as

$y+120+85+53=360$

now, we can combine it

$y+258=360$

now, we can subtract both sides 258

$y+258-258=360-258$

$y=102$

so, this is FALSE..........Answer
