If u separate these into 2 triangles then they will become 90 degree triangles so angle a=angle c.
Answer:
Please check the explanation.
Step-by-step explanation:
We know that when a consistent system has infinite solutions, then the graphs of the equations are exactly the same. In other words, these equations are called dependent equations.
All points of dependent equations share the same slope and same y-intercept.
For example,
6x-2y = 18
9x-3y=27
represent the dependent equations.
Writing both equations in slope-intercept form
y=mx+c
where m is the slope and c is the y-intercept
Now
6x-2y=18
2y = 6x-18
Divide both sides by 2
y = 3x - 9
Thus, the slope = 3 and y-intercept = b = -9
now
9x-3y=27
3y = 9x-27
Divide both sides by 3
y = 3x - 9
Thus, the slope = 3 and y-intercept = b = -9
Therefore, both equations have the same slope and y-intercept. Their graphs are the same. Hence, they are called dependent equations.
R = 13.1
so
<span>diameter = 13.1 x 2 = 26.2 km
</span>circumference = 2 pi r = 26.2 pi km
or
circumference = 26.2 x 3.14 = 82.27 km
True ACTUALLY helped? Click on thanks and rate also if u want Mark me as brainliest plz =)
Answer:
No
Step-by-step explanation:
The inequality will not be the same if the same amount is added both sides.
The addition property states that if the same quantity is added to both sides, then the inequality still remains true. Take for example:
let x, y, and z be real numbers. It follows that:
if x ≥ y, then x + z ≥ y + z
This holds true for whatever value of z
If x ≤ y, then x + z ≤ y + z
The inequality remains true.
