47/9+110/15=705/135+990/135=1695/135=12 15/27
Explanation
Step 1
find the coordinate of every point of the quadrilateral
C(-3,1)
J(0,1)
K(1,4)
M(4,-2)
Step 2
When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed).
so
therefore
so, the answer is
i hope this helps you

Answer:
Step-by-step explanation:
The rhombus has several relevant properties.
- The sides are all the same length
- Diagonals are perpendicular bisectors of each other
- Diagonals divide the rhombus into congruent triangles
The last of these relations can be used to find x:
7x° = 35°
x = 35°/7° = 5
The second of the relations can be used to find y:
3y° = 90°
y = 90°/3° = 30
The first of the relations can be used to find z:
10z -8 = 5z +32
5z = 40 . . . . . . . . . add 8-5z
z = 40/5 = 8
