Step-by-step explanation:
Based off of what we do know, if we can find length DB we can use the pythagorous theorem (I will be assigning the variable z)
First equation is for triangle ABD
Second is for BCD
And the last one is for ACD
Substitute 
and 
As discovered before
8.125. Just divide the number of bags they collected together.by how many of them collected them, to find out how many each of them collected
To work out 10% you divide it by then. 10% of 30 is 3. To get 80% from 10%, you times it by 8. 3X8=24
