Supplementary angles sum to 180°
180-27=153°
56 /2 = 28
35^2 - 28^2
= 1225 - 784
= 441
= 21
base of triangle = 21 x 2 = 42
area of triangle = 1/2 bh = 1/2(42)(28) = 558
area of rhombus = 558 x 2 = 1176
answer
B . 1176 in^2
Answer:
an = -6*(1/4)^(n-1)
Step-by-step explanation:
We have that the recursive formula for the given geometric sequence is:
a1 = -6
an = (an-1) * (1/4)
With the above we can assume that:
r = 1/4
following the rule of the explicit formula that is given by:
an = a1 * (r) ^ (n-1)
we substitute and we have:
an = -6 * (1/4) ^ (n-1)
Therefore the explicit formula from the given data would be:
an = -6 * (1/4) ^ (n-1)
