Calculate the value of OK.

Answer:
8.5
Step-by-step explanation:
To do this you must set up a proportion:
[tex]\frac{small}{big} =\frac{small}{big}[/tex]
Let x= OK
[tex]\frac{2}{x} =\frac{4}{17}[/tex]
Use cross multiplication to solve for x:
[tex]4x=34[/tex]
[tex]x=8.5[/tex]
The length of OK equals 8.5
