Step-by-step explanation:

Yes, because angle 1 and angle 5 are congruent.

Step-by-step explanation:

Two parallel lines cut by a transversal form special angles with special relationships. Angle 1 and angle 5 are corresponding angles and therefore are congruent. They are both top left of their respective angle groups.

the answer is a

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
