Surely each angle in the polygon is 3 x 180 / 5 = 108 degrees...
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.
