Question

answer choices:
a. 122
b. 102
c. 138
d. 85

Answer 1

Answer:

option b

Step-by-step explanation:

The sum of the interior angles of a quadrilateral is 360°.

That is,

     120 + y + 85 + 53 = 360

              y = 360 - 120 - 85 - 53

              y = 102

Answer 2

Answer:

Option B is correct

Step-by-step explanation:

Hint :

Sum of angles in quadrilateral = 360°

Simplify :

${y}^{o} + {120}^{o} + {85}^{o} + {53}^{o} = {360}^{o} \\ {y}^{o} + {258}^{o} = {360}^{o} \\ {y}^{o} = {360}^{o} - {258}^{o} \\ {y}^{o} = {102}^{o}$
