Answer:
x < - 3
Step-by-step explanation:
If you reflect across the x-axis, the y value change from positive to negative.
If you reflect across the y-axis, the x value changes from positive to negative
Given:
The figure of a pentagon.
To find:
The value of the x.
Solution:
We know that, the sum of all interior angles of a pentagon is 540 degrees. So,



Subtract both sides by 12.


Divide both sides by 33.


Therefore, the value of the x is 16.
Answer:
Distance: 13, Midpoint: (-2, 3.5)
Step-by-step explanation:
The distance formula is
. We can plug in the numbers from your question so it would be √(4+8)^2+(6-1)^2 = √144+25=169 =√169 = 13
The midpoint formula is ((x1+x2)/2, (y1+y2)/2), which is -8+4/2, 1+6/2 = (-2, 3.5).
