Answer: 127º
Step-by-step explanation: The sum of internal angles from a polygons is equal to 180 (n-2) where n is the number of sides for the polygon
so the polygon from the picture has 6 sides then the total sum of internal angles is:720º
On the other hand, added all the internal angles we have: 112º+133º+128º+100º+120º=593º
the angle denoted by x is equal to 720º-593º= 127º
Answer:
$1.76
Step-by-step explanation:
when you multiply 2.20x 0.8 you get 1.76. at first I thought division was needed, but the answer to 2.20/0.8 is 2.75- which is more than the original cost. (sorry if this is confusing but) 0.8 pound is less than 1 pound, so the answer would need to be less than 2.20.
