Let's solve this in two parts, first the equation. Let x represent the ages of the daughters, so the equation is
x + (x+2) + (x+4) = 60
Next let's calculate the ages.
3x+6=60
3x=54
54/3=18, therefore x=18
x=18
x+2=20
x+4=22
So the ages of the daughters are from youngest to oldest are 18, 20, and 22

Answer:
i) ∠AOB = 87°
ii) ∠BOC = 72°
iii) ∠COD = 123°
iv) ∠AOD = 78°
Step-by-step explanation:
The first three angle measures can be read from the diagram. Find the rays that define the angle, and read the measure of the arc between them.
The last angle, AOD, is found using the fact that the sum of all of the angles around a point is 360°.
87° +72° +123° +∠AOD = 360°
∠AOD = 360° -282° . . . . . . . . . . subtract 282° from both sides
∠AOD = 78°
