1/4*x - 1/6*y= 5 |*18
4/5 *x + 3/8*y = 10 | *8
18/4*x -3*y= 90
32/5*x + 3y = 80
-------------------------
18/4*x+32/5*x / = 170
The answer is a
Answer:

I don't remember equation but I know this is the because I can roughly estimate the numbers by dividing by four and going from there
The sum of a trapezoid is 360 degrees
45+90+90+x=360
45+180+x=360
225+x=360
x=135
