X+ 2. Here are the first three stages of a sequence of dots. If we drew each of the first 15
stages, how many dots would we have to draw? Select all of the expressions
representing this number.
A. 3(1 + 3 + 32 +...+3^14)
B. I-315
1-3
C. (1 - 3)(1 + 3 + 32 +...+3^14)
D. 31-
E. 3(1 - 3)(1 + 3 + 32 +... +3^14)

all the angles opposite to the angle 150 would be 150 and all the angles that are next to 150 are 30 because they equal 180 it you add it up.

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.
