explain how i got the answer and include example to go with answer above break down how you would got the example

the answer to your question a or b but i am pretty sure it is b. i hope this : )

step-by-step explanation:

i dony know

step-by-step explanation:

goog may have it for you

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.
