Answer:
1st Graph:
Add all the numbers (Do the same to 2nd Graph)
Then add
answer will be shown
1 hour is 15m
2 hour is 30m
3 hour is 65m
4 hour is 80m
Use distance formula:-
distance = sqrt [ (x2 - x1)^2 + (y2 - y1)^2) ]
let (x1,y1) = (-3,1) and (x2,y2) = (-1,6) Plug these values in to formula.

The hypotenuse is 5 unit and the adjacent side to the angle is 4 unit. We can find the other side using Pythagoras theorem

Hence the value of
