I'll be making an example graph that only goes up to 13 here.
Age - 10 11 12 13
Height
v
6ft
5ft
4ft
If we mark this graph with points, you will find that there is only 1 point on each age line!

Height
v
6ft *
5ft * *
4ft *

Step-by-step explanation:
Cos C =
<em>Where Adjacent = 24 , Hyp = 40</em>
Cos C =
<u><em>In simplest form</em></u>
