Answer:
i think -11
Step-by-step explanation:
False. If the area is 0 that means there is nothing there, therefore the area of a polygon cannot be zero.
Answer:
x=89
Step-by-step explanation:
180-91=89
Answer:
x = 51
Step-by-step explanation:
The figure shown is a pentagon
The angles in a pentagon add up to equal 540
Which means that 77 + 107 + 156 + 149 + x = 540
^ ( note that we just created an equation that we can
use to solve for x )
We then solve for x using that equation
77 + 107 + 156 + 149 + x = 540
step 1 combine like terms
77 + 107 + 156 + 149 = 489
we now have 489 + x = 540
step 2 subtract 489 from each side
489 - 489 cancels out
540 - 489 = 51
we're left with x = 51
Answer:
See below.
Step-by-step explanation:
It is the one at the top left side.
The line y = x passes through the origin at an angle of 45 degrees to the x axis and rises to the right.
So if you imagine its a mirror you'll see that its a reflection in that mirror.
