C. 32
Step-by-step explanation:
There are 16 lines of symmetry passing through the vertex's and another 16 passing through the mid points of the sides
Hope this would help you!!!
No, as Anglel has 0.5 yards and Lynn has 0.75 yards
The number=10x+y
we suggest this system of equations:
(10y+x)-(10x+y)=27
x+y=9 ⇒x=9-y
Can solve this system of equations by susbstitution method.
(10y+(9-y)-(10(9-y)+y)=27
10y+9-y-(90-10y+y)=27
10y-y+10y-y=27-9+90
18y=108
y=108/18
y=6
x=9-y
x=9-6
x=3
The number=10x+y=10(3)+6=36
Answer: the number is 36.
to check:
63-36=27
6+3=9
Answer:
m<1= 128 degree ( being alternate angle)
m<2
= 180degree - 128degree ( being cointerior angle)
=52degree
m<3= 138degree being corresponding angle)
