Answer:

d. x = 19, y = 16

Explanation:

Given quadrilateral is cyclic.

Opposite angles of a cyclic quadrilateral are supplementary.


5x \degree + 85 \degree = 180 \degree \\ 5x \degree = 180 \degree -85 \degree \\ 5x \degree = 95 \degree \\ x = (95)/(5) \\ \huge \red{ \boxed{ x = 19}} \\ \\ (4y + 4) \degree + 112 \degree =180 \degree \\ 4y\degree + 4\degree + 112 \degree =180 \degree \\ 4y\degree + 116 \degree =180 \degree \\ 4y\degree =180 \degree - 116 \degree \\ 4y\degree =64 \degree \\ y = (64)/(4) \\\huge \purple{ \boxed{ y = 16}}

The Answer is A

5x=85 (to find the x get the x alone so divide 5 from 5x and also do the same on the other side with 85)
112=4y+4 (minus 4 from 4y+4 and minus 4 on the other side as well with the 112, 112-4=108
108=4y (get the y by itself so divide 4 from 4y and divide 4 from 108 as well, 108/4= 27)
