Idon’t understand this.. will someone ? will mark brainliest along with 20 points.

The angle of a triangle are given as 6x,(x-3), and (3x+7). find x then find the measures of the 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.
