Step-by-step explanation:
D. the corresponding sides of triangle ABC and triangle A'B'C' are congruent
because the sides do not change their length when we rotate the triangle
Distribute:
3x-12=12
Add 12 over
3x=24
divide by 3
x=8
i am edditing my post because i got the answer wrong
The answer to your question is 54 because you have to bring over 2 to 3 and it would be 1x then bring over 52 and add it to 2 = 54
Answer:
Circumference is pi times diameter so that would equal 15 pi. The formula to find the area of a circle is A=pi * r^2 So you divide 15 by 2 to find the radius. r=7.5 Then you square it and multiply it by pi and get 56.25pi which is about equal to 176.715
