If vertex Penguins can reach vertex Capitals and vertex Capitals can reach vertex Islanders, but none of them can reach vertices Sharks or Ducks, what can you say about the set of vertices Penguins, Capitals, and Islanders

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.

answer: none of these answers are correct only the second half is
