When reflecting over a line, the first step is to Find the slope of the line of reflection.
Find the perpendicular slope.
Count slope triangles to find the distance of the pre-image to the line of reflection.
Flip the pre-image over the line of reflection.

the axial of symmetry

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.

the answer is  

a.
