Question

Find the value of each missing variable x and y

Answer 1

b x = 94, y = 105

Explanation:

x = 180 - 86 = 94 supplementary

interior angles of quadrilateral: 180 x (4 - 2) = 360

y = 180 x (4-2) - 72 - 89 - 94 = 360 - 72 - 89 - 94 = 105

Answer 2

B.x=94, y=105

Explanation:

Let's start with x

x is places in a supplementary angle

supplementary angles are equals to 180 so

180-86=94

Next the y

interior angles have a formula 180(n-2)

so there are 4 sides

180(4-2)

180(2)

=360

add all the angles then subtract it to 360

72+89+94+y=360

255+y=360

y=360-255

y=105
