Let Angle A = X
Since Angle B is the same, angle B is also X
Then angle C = X +45
Add the 3 angles together: X +X +X +45 = 3x+45
That equals 180 degrees:
3x+45 = 180
Subtract 45 from both sides:
3x = 135
Divide both sides by 3:
X = 135/3
X = 45
Angle A = 45
Angle B = 45
Angle C = 45+45 = 90

Answer:
perpendicular
Step-by-step explanation:
The graph of x = 4 is a vertical line and the graph of y = 3 is a horizontal line.
Vertical and horizontal lines are perpendicular.
