Answer:
k = 7
m = 8
Step-by-step explanation:
The diagonals of a parallelogram bisect each other, so the two halves of each diagonal are the same length. That means ...
m = 8
and
k +4 = 11
k = 7 . . . . . subtract 4 from both sides of the equation
Answer:
X = 13
y= 54
Step-by-step explanation:
9x-7=7x+19 (vertical opposite angle)
9x-7x=19+7
2x=26
X=13°
now ,
(9x-7)= 9x13-7=110
(9x-7)+(y+16)=180 sum of the straight angle
110+y+16=180
y=54
