Consider the diagram. Why are lines AC and RS skew lines? They lie in different planes and will never intersect. They lie in the same plane but will never intersect. They lie in different planes but will intersect if a plane is drawn to contain both lines. They lie in different planes and will be parallel if a plane is drawn to contain both lines.

step-by-step explanation:

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.

c.

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2
