We have been given a diagram and we need to find the value of arc angle a.
According to one of the circle theorems the angle at the centre of a circle is twice the angle at the circumference subtended by the same arc.
Therefore, arc angle a will be twice of the angle at circumference, that is, 34 degrees.
Therefore, value of angle a is:
The y is going to be 165 if the x is 54 because you need to multiply by 3 each time.
C Becuase it’s the same triangle but doubled
To convert the amount of milk from deciliters to liters we proceed as follows:
1 liter = 10 deciliters
therefore the amount of liters used in making the cake will be found as follows:
5.25/10×1=0.525 liters
Answer: 0.525 liters
