Kellianne lined up the interior angles of the triangle along line p below.
Which statements are true for line p? Check all that apply.

E, G, and H

Step-by-step explanation:

E: The sum of a triangle's angles is always 180 degrees. The angle of a straight line is ALSO 180 degrees.

G: The triangle's angles combined are all on the straight line, forming 180 degrees.

H: As stated previously, straight lines always have an angle of 180 degrees.

the solution is h=10 because you add 9 to each side of the equation.
