Answer:
True
Step-by-step explanation:
• Parallel lines have equal slopes
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
6x + 3y = 7 ( subtract 6x from both sides )
3y = - 6x + 7 ( divide terms by 3 )
y = - 2x + 
→ in slope- intercept form
with slope m = - 2
y = - 2x + 3 ← is in slope- intercept form
with slope m = - 2
since both lines have equal slopes then they are parallel lines
You need to find the value of y..
40=8y
40÷8=y
5=y
The value of y is 5

Answer: 56 degrees</h3>
===================================================
Work Shown:
For any triangle, the three interior angles always add to 180
(4x-12) + (6x-17) + (2x+5) = 180
(4x+6x+2x) + (-12-17+5) = 180
12x - 24 = 180
12x = 180+24 ..... adding 24 to both sides
12x = 204
x = 204/12 ..... dividing both sides by 12
x = 17
We can use this x value to find the three angles
4x-12 = 4*17-12 = 56
6x-17 = 6*17-17 = 85
2x+5 = 2*17+5 = 39
As a check,
56+85+39 = 180
which confirms we have the right x value.
We see that 56 is the middle angle, so this is the second largest angle.
-7+n=12
this leaves us with n=19
