Angle 3:
62+47=109
All angles in a triangle add to 180 degrees, so 180-109= 71 degrees
Angle 2:
Angles in a straight line always add to 180 degrees too,
so 180-62= 118 degrees
Angle 1:
Again, angles in a triangle add to 180,
so 180-22-118= 40 degrees
Angle 1: 40
Angle 2: 118
Angle 3: 71
Hope that helps :)
The distance would be, ((x1-x2)^2+(y1-y2)^2)^0.5
x1=-7,y1=9, x2=-4,y2=2
hence distance = sqrt(9+49) = sqrt (58) = 7.615773106
Answer:
a
Step-by-step explanation:
Assuming your first equation is y = 5x+9, the equations describe lines that are coincident.
_____
Multiplying the second equation by -1, it becomes y = 5x+9, the same as the first equation.
