Answer:
the origin
Step-by-step explanation:
The standard form would be y = 7x^2 - 42x + 67
for this case we have to define trigonometric relations of rectangular triangles, that the tangent of an angle is given by the leg opposite the angle on the leg adjacent to the angle. So:

Answer:

1)Add up the numbers and variables.
2) Triangles equal 180 degrees.
3)Subtract the total of the numbers and 180.
4) Then divide by the variable.
X= -10
