11. IF PORS is a parallelogram, find the values of x and y.
11. X
y
(10y - 7

x = 4 and y = 15

Step-by-step explanation:

Opposite sides of parallelogram are equal

Opposite sides of parallelogram are equaltherefore,

13x + 15 = 19x - 9

15or 15 + 9 = 19x - 13x

or 24 = 6x

or 24÷6 = X = 4

adjacent angles = 180°

therefore,

(10y - 37) + (4y + 7) = 180

or 10y - 37 + 4y + 7 = 180

or 14y = 180 + 37 - 7

or 14y = 210

or y = 210 ÷ 14

or. y = 15
