Answer:
Part A: 0
Part B: (-1,-1) since point (-1,1) is located in quadrent four when it is reflected over the y axis the second point would be located in quadrent three and the x and y would both be negative.
Step-by-step explanation:
The total would be $26.13
Consider this option:
1. to simplify given expression (a-b)/b:
![\frac{a-b}{b}= \frac{a}{b}-1;](https://tex.z-dn.net/?f=%20%5Cfrac%7Ba-b%7D%7Bb%7D%3D%20%5Cfrac%7Ba%7D%7Bb%7D-1%3B)
2. to rewrite given expression a/4=b/7:
![\frac{a}{b} = \frac{4}{7};](https://tex.z-dn.net/?f=%20%5Cfrac%7Ba%7D%7Bb%7D%20%3D%20%5Cfrac%7B4%7D%7B7%7D%3B)
3. to substitute a/b into the simplified expression:
![\frac{a}{b} -1= \frac{4}{7} -1=- \frac{3}{7};](https://tex.z-dn.net/?f=%20%5Cfrac%7Ba%7D%7Bb%7D%20-1%3D%20%5Cfrac%7B4%7D%7B7%7D%20-1%3D-%20%5Cfrac%7B3%7D%7B7%7D%3B)
answer: -3/7
Since you know the given angle is 46deg. You also know that a straight line is equal to 180deg. So it's a supplementary angle, therefore you subtract 46 from 180 and get 134. And since the l, m, and n are parallel, they have congruent angles. So x = 134deg.
