Answer:
A
Step-by-step explanation:
Because the angle with measure 124 degrees and angle y are a linear pair, their values must add up to 180 degrees. Therefore, y=180-124=56 degrees. Since all of the angles in a quadrilateral add up to 360 degrees, x must be 360-56-65-125=114 degrees. This means that the correct answer is choice a. Hope this helps!
They are perpendicular because they both meet at (5.5,-2.5)

1/5 is your answer, sorry if it is wrong but I think it os right :)
Step-by-step explanation:
Given that,
a + 2b = 17
Also,
2a + b = 4
By adding the above expressions we get,
a + 2b + 2a + b = 17 + 4
3a + 3b = 21.
3 (a + b) = 21
a + b = 21/3
a + b = 7 Let us take 'b' = 10
a + 10 = 7
a = 7 - 10
a = -3
Now let's check by verifying by putting a = -3 and b = 10 in the previous expressions
a + 2b = 17
-3 + (2 × 10) = 17
-3 + 20 = 17
17 = 17
2a + b = 4
(2 × -3) + 10 = 4
-6 + 10 = 4
4 = 4
Therefore, a = -3 and b = 10 [(-3,10)] is the solution.
