Answer:
y = -3x-1 or 3x + y = -1
Step-by-step explanation:
6x + 3y - 11 = 0 can be written as y = -3x + (11/3)
In parallel lines the slope remains the same but the constant changes. To find the constant you place in the cordinates for x and y.
5 = -3(-2) + b
5 = 6 + b
5 - 6 = b
-1 = b
Now you replace (11/3) by the new b, -1
y = -3x - 1
Answer:
1st angle = X
2nd angle = X + 7
3rd angle = X + 18
Then (sum. them): 3X + 25 = 180 ==> X = 51.67 degree
Therefore,
1st angle = 51.67 degree
2nd angle = 58.67 degree
3rd angle = 69.67 degree
