Answer
A. 196,608
Step-by-step explanation:
-12/3 = -4
48 / -12 = -4 and -192 / 48 = -4
This is a geometric sequence with common ratio -4.
an = a1 r^(n -1) so:-
9th term (a9) = 3*(-4)^(9-1)
= 196,608

Answer: The length of
is 30.
Step-by-step explanation:
-According to the figure, Δ
is congruent to Δ
.
So, if the length of
is 30, then the length of
is also 30, because
.
Because base angles are congruent, both angle A and B are congruent. If the two triangles are congruent, then the base angles are the same, meaning 5x=50*. Divide by 10 and you get the answer of x=5. :) Hope this helps!
