What am I supposed to be helping with the picture you took is only showing examples
Z = 140
X = 40
Y = 40
Explanation:
Z and the angle given (140 degrees) are vertical angles, and are therefore congruent
We know that x and y are vertical angles, so they are also congruent to each other
You know that together, the angles have to add up to 360
140 + 140 + x + y = 360
Another way of putting it:
360-280 = 80
Now, we have to divide by two since we need to find x AND y
80/2 = 40
Therefore, your answers for x and y are 40
To double check, you can add up the angles and see if they equal 360
140 + 140 + 40 + 40
280 + 80 = 360
The nearest ten thousand of 63849 would be 60000
I think the answer is 2476/825
Answer:
4.62910049578
Step-by-step explanation:
variation is standard deviation squared
variance = 21.428571428571
square root variance for answer.
