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
Step-by-step explanation:
16 - 4(3x - 5)
16 - 12x + 20
12x = 16 + 20
12x = 36
x = 36/12
x = 3
Answer:
9
Step-by-step explanation:
Because the Y's cancel out you add the absolute value of negative 5 and 4.
