One of the same side angles of two parallel lines is 20° smaller than the other one. find the measures of these two angles.

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.

Solve for b. ab + c= d b= a + old ob=allc-ch b= (d-c/a
