Hey Guys,

I need some help finding the value of the variable.

I know you will need to use sine for this one but I don't know what numbers to use.

I know it's a regular polygon with 5 sides so that means each angle is 72.

I don't know what the next step would be.

State the ratio needed, and use it to findthe measure of the indicated line segment to the nearest tenthof a unit.
