Answer:
7groups
Step-by-step explanation:
15+6/3=7groups
Both variables (x) are 3.
4×3=12
12-2=10
16×3=48
48-8=40
3 fits the variable of the missing number.
The surface area of that cube is 8.64 cm
X=105°
Y=105°
Z=105°
let the angle below 75° which is the 4th Street be A
75°+A=180°[being adjacent angle]
A=105°
X=A[Verticall opposite angle]
Z=A[Corresponding angle]
Y=X[alternate angle]
