Answer:
this is true because you can divide 8/10 by 2 and you get the same number 2/5 and sorry for my english
Answer:

Step-by-step explanation:
Start by finding the slope of the given line.

Slope of given line




A perpendicular bisector cuts through the line at its midpoint perpendicularly.
The product of the slopes of two perpendicular lines is -1.
Let the slope of the perpendicular bisector be m.




, where c is the y-intercept.
To find the value of c, we need to substitute a pair of coordinates that lies on the perpendicular bisector into the equation. Since the perpendicular bisector passes through the midpoint of the given line, we can use the midpoint formula to find the coordinates.

Midpoint of given line


= (0, 2)

When x= 0, y= 2,
2= ⅔(0) +c
2= 0 +c
c= 2
Thus, the equation of the perpendicular bisector is
.
The lengths of sides a and c add to 9 cm, the length of side b.
In a triangle, the the sum of the lengths of any two sides must be greater than the the length of the third side. These dimensions do not make a triangle.
Is this really what you meant? Why did you use capital A for a side? Or is A an angle, and it measures 6 deg, not 6 cm?
Answer: 90 degrees
Step-by-step explanation:
Same-side interior angles thm states that the 90 deg angle and angle 3 are supplementary.
take the number to the right of the underlined digit. if its 4 or less, the digits of the underlined one to the left stay the same, while the digits on the right are turned into 0's.
I'll do a few to help you out:
1. *1*60,656 = 200,000
2. *1*49,590 = 100,000
3. 117,*8*21 = 117,800
