Answer:
144°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° × (n - 2) ← n is the number of sides
Here n = 8 ( octagon ), hence
sum = 180° × 6 = 1080°
let the measure of 1 congruent angle be x
Then sum the 8 angles and equate to 1080
100 + 120 + 140 + 5x = 1080
360 + 5x = 1080 ( subtract 360 from both sides )
5x = 720 ( divide both sides by 5 )
x = 144
Thus each of the 5 congruent angles is 144°

How much is a pair of jeans? I can not answer the question if I do not know the price of the jeans.
area of this parallelogram=b×h=13×6=72inches
<span>100 = 5 * (5+5+5+5)
</span><span>100 = (5*5*5) - (5*5)
</span><span>100 = (55/.5) - (5+5)</span>
