Chords ac and bd intersect at the center of circle abcd. which is the measure of the minor arc ab? a) 20 b) 45 c) 60 d) 75

b. 18

step-by-step explanation:

so the equation for this is:

ab^2=ac⋅ad

ab being the top length of 6 and ac being the length of 2 and ad being the length of x. let's plug into the equation:

6^2 = 2x

now lets just solve for x:

36 = 2x

18 = x

i hope that !
