Answer:
No they do not have to be congruent.
Answer:
So since the sum of both is 13 because it shows both of the lines connected as a length of lines.
So we add them (14+x)+(x+15) = 13
14+2x+15 = 19+2x = 13
-6=2x
x=
<u>-3</u>
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
We know the formula is pi * r^2 * h, so we can do 108/12.
We end up getting 9. Then we take the square root of 9 since 9 = r^2 so our r does equal to 3
