Answer 1

Answer:

Step-by-step explanation:

Let say circumference  = C

C = pie * Diameter = (22/7) * BC

arc AB = (30/360) * C = C/12

arc AC ( (180-30)/360 * C = 5C/12

arc ACB = C - arc AB = C -C/12 =  11C/12

Answer 2

let the radius be of r units thus
1. Measure of arc AB=30/360×2πr
1/6πr units
2.Ac=150/360×2πr
5/6πr unit
3.ACB=320/360×2πr
16/9πr unit.
