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.

you could deduce the conclusion directly using the facts pertaining to the specific situation.

hope this .

a reflection across the x axis and a 90 degree rotation left and right.

my answer was deleted because it was to vague the answer is 12.76 becuase its in the hundreths place. john
