In the figure below, AB is a diameter of circle P. What is the arc measure of minor arc AC in degrees?

111degrees

Step-by-step explanation:

ArcAC + arcBC = 180

Given theat arcBC = 69degrees

arcAC + 69 = 180

arcAC = 180 - 69

arcAC = 111

Hence the length of minpr arc AC is 111degrees

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:

answer: answer is b.

[m < b = 120º]
