For a regular 8 sided polygon each angle against each side, is 360/8=45.

So x=45/2=22.5

Then

\tan(22.5)  =  \frac{y}{8} \\ and \: we \: know \:  \tan(22.5)  =  \ \sqrt[]{2}  - 1 \\ so \: y = 8( \sqrt[]{2}  - 1)

Dima020 [189]

Answer:

The value is 50.6cm

Step-by-step explanation:

In order to find this , set up a proportion. Use the smaller part of the triangle on top, and the corresponding part of the larger on bottom.

32.2/46.2 = x/72.6

Now cross multiply to solve

72.6*32.2 = 46.2*x

2337.72 = 46.2x

50.6 = x
