I believe the correct answer is 9
Its 61. So 47+72 which equals 119 then subtract from 180 to get 61
The answer is -16. Here's the explanation:
3 x - 10 = 5x + 22
3x - 5x = 22 + 10
-2x = 32
x = -16.
I hope this helped you!!!!!! :)
Step-by-step explanation:
the x distance from A to B is 3 (from -1 to 2), and the y distance is 15 (from -4 to 11).
the x distance from C to D is also 3 (from 1 to 4), but the y distance is 9 (from 1 to 10).
so, the slopes are different
AB : 15/3 = 5
CD : 9/3 = 3
and the lines are therefore not parallel.
perpendicular slopes are simply inverting y and x in the ratio and flip the sign (from - to + and vice versa). but that is not the case here either (just to start - both slopes are positive).
so, the 2 lines are "neither".
