Answer:
B. SSS similarity theorem
Step-by-step explanation:
Both triangles would be similar if the ratio of their corresponding sides are equal, based on the SSS Similarity theorem. That is:
AC/XZ = CB/ZY = AB/XY
Let's find the value of x using CB/ZY = AB/XY
x/2 = 9/3
x = (9*2)/3
x = 6
Thus:
AC/XZ = CB/ZY = AB/XY = 3
The ratio of their corresponding sides is equal to 3. Therefore, based on the SSS similarity theorem.
Edit: Misread the diagram, the previous answer was wrong.
The answer is 125/18. decimal form would be 6.94 (repeating) lol
A.
n=1 is -4*1=-4
1st term is -4
2nd is -4/3
3rd is -4/9
4th is -4/27
b. converge because -1<r<1
c. as long as -1<r<1, then
the sum of the infnite series is
a1=-4
r=1/3
=
=-12/2=-6
it has a sum of -6
sum of gemoetric sequence is
a1=6
r=2
n=10
6138
2nd answer
3*5+4*5+5*5+6*5+7*5+8*5=
5*(3+4+5+6+7+8)=
165
answer is 4th one
There's no way for us to use the table if you won't share it with us.
