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
Pretty sure that it is 9/7.
Answer:
Step-by-step explanation:
<u>Reflection over x-axis results in:</u>
- f(x) → - f(x) translation
<u>Therefore the new function is:</u>
The ratio is 10:14 or 5:7 which is the ratio of boys to girls!
