Complete the following proof.
Given: Two concentric circles with AB tangent to smaller circle at R
Prove: AR = RB

not solvable

step-by-step explanation:

we need more information, or at least an

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:

a = 3.14

b = 18

c = 18/5 or 3.6 or 3 3/5
