In this diagram, which is not drawn to scale, DE, DF and DG are the perpendicular bisectors of AABC. Given: BC= 30 and DC = 17. Find DE
Enter the correct answer in the box.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

mx+89b(-98)nb
