Answer:

Step-by-step explanation:

The angle at the centre of a circle is twice the angle at the circumference for angles subtended by the same arc.

∠DAR and ∠DBR are both subtended by the arc RD, hence

∠DAR = 2∠DBR = 2 × 34° = 68°

Darnel needs to spend three days making jam if he wants to jar 15 liters.

Step-by-step explanation:

If you are to assume the relationship is proportional then if he makes 10 liters in 2 days you divide 10 by 2 and you get 5. This means he makes 5 liters a day. Then you add 5 to 10 and you get 15 which means you are adding another day(5) So he needs to work an extra day which would give you three dyas total. Hope this helped!
