Twice means times 2.
1) 2(ab) gives twice the product of a and b.
2) (2a)b gives the product of twice a and b.
Answer:
Step-by-step explanation:
See the attachment for the chart
It would be (2,1)
y=-2*2+5
y=-4+5
y=1
The missing angle is 130 degrees.
The sum of all the angles of a hexagon equal 720 degrees. So, you'd add all the known angles together (this gives you 590), then subtract that from 720. Thus getting 130 degrees as a final answer.
I hope this helps!
