When solving a system of equations by elimination, there are multiple correct ways you can start. Which of the following is NOT a correct first step?

the first one, all those points on the line just make a strait line.

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.

umm im not really sure because i never had to do this

step-by-step explanation:

d is ur answer hopes this i dont really know how to explain it to u.
