Answer:
B. 0
Step-by-step explanation:
The circles do not intersect, tangents require intersection
D means common difference which is the last term minus second last term .
and u can use this formula only if there is a common difference.
Answer:
cos 45 degree = A/H
cos 45 degree = 2 square root 2 / x
x = 2 square root 2 / cos 45 degree
x = 4
Sin 45 degree = O/H
Sin 45 degree = y/ 4
4 x Sin 45 degree = y
y = 2.83
or
we could use tan
tan 45 degree = O/A
tan 45 degree = y / 2 square root 2
2 square root 2 x tan 45 degree = y
y = 2.83
i hope this would elp a little bit.
I'm not sure if you mean (
) or (
) I solved it both ways .
