Answer:
A Yes, a sequence of dilations and rigid motions carries one triangle onto the other
Step-by-step explanation:
Since two angles are marked with the same measures in each triangle, the triangles are similar by the AA postulate with no further action.
By some accounts it seems to be necessary to lay one figure on top of the other to demonstrate similarity. In order to do that, the smaller triangle would need to be dilated and translated (a rigid motion) to make it occupy the same space as the larger triangle.
Answer:
15/x-2
Step-by-step explanation:
Cant attach the photo but you use a division table
To find the length of each side 72/4
Each side is 18
So area is 18 times 18= 324
To make it easier, aprox pi=3.14
area=pir^2
36=area
36=pir^2
divide both sides by pi
36/pi=r^2
36/3.14=r^2
11.464=r^2
square root both sides
3.39=r
circumfernce=2pir
r=3.39
circumfrence=2pi times 3.39
circumference=pi times 6.78
circumference=3.14 times 6.78
circumfernce=21.29
answer is
circumference=21.29 in
