Answer:
14
Step-by-step explanation:
84/6
? = 13
Using Pythagoras' identity in the right triangle
?² = 5² + 12² = 25 + 144 = 169 ( take the square root of both sides )
? = = 13
The answer is 5f + 6g +12
are the Fibonacci numbers,
0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, ...
Taken modulo 7, we get the sequence
0, 1, 1, 2, 3, 5, 1, 6, 0, 6, 6, 5, 4, 2, 6, 1, ...
that repeats with period 16 (this is known as the 7th Pisano period).
This is to say,
so that
The total surface area can be calculated using the formula
From the diagram
We plug in these values to get;
i think its A im not sure
