The geometric sequence that tells the perimeter of each stage in the building of koch's snowflake has a first term of 3 and a ratio of 4/3. at the 18th stage in the construction of this snowflake, the length of each tiny side would be about the size of an atom! using the explicit formula for the nth term of a geometric sequence, what is the length of the perimeter a18 to the nearest whole number? a. 399 b. 299 c. 200 d. 133 e. 99

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
