Answer:
9
Step-by-step explanation:
To solve this, you need to find the proportion.
p is a leg of the large triangle, and the leg to the small triangle is 6.
8 is another leg of the small triangle, and 8+4 is the leg of the large triangle.
So [tex]\frac{small triangle}{big triangle} = \frac{small triangle}{big triangle\\}[/tex]
[tex]\frac{8}{12} =\frac{6}{p}[/tex]
[tex]\frac{2}{3} =\frac{6}{p}[/tex]
cross multiply to get 2p=18
divide both sides by 2
p=9.
