Question

Circle K has arcLM,arcMN,and arcNL. The ratio is 5:3:4, find each measure of each arc.

Answer 1

the first step will be that you know a circle has 360 degree

so this 360 degree just you need dividing in this 3 parts but in a ratio of 5:3:4

hope this will help you

Answer 2

next add 3 , 4 and 5 = 12
so the fraction of each arc is 3/12 , 4/12 and 5/12

Answer 3

so measure of smallest arc = (3/12) * 360
Caculate the other 2 in a similar way.
