You have two 30-60-90 triangles, ADC and BDC.
The ratio of the lengths of the sides of a 30-60-90 triangle is
short leg : long leg : hypotenuse
1 : sqrt(3) : 2
Using triangle ADC, we can find length AC.
Using triangle BDC, we can find length BC.
Then AB = AC - BC
First, we find length AC.
Look at triangle ACD.
DC is the short leg opposite the 30-deg angle.
DC = 10sqrt(3)
AC = sqrt(3) * 10sqrt(3) = 3 * 10 = 30
Now, we find length BC.
Look at triangle BCD.
For triangle BCD, the long leg is DC and the short leg is BC.
BC = 10sqrt(3)/sqrt(3) = 10
AB = AC - BC = 30 - 10 = 20

Answer:
y=5x
Step-by-step explanation:
Given no of bags is x
No of apples in each bag is 5
Thus no of apples in x bags can be obtained by multiplying no of bags(x in this case) with No of apples in each bag (5 in this case).
Total no of apples in x bag = 5*x = 5x
As y represent relationship between number of apples and bag. 5x will be equal to y.
it can be represented as y = 5x
Thus equation A y=5x shows the relationship between the number of apples, y, and the number of bags, x
