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
