hello! I would need some help with this question, I have tried it a few times and got different answers everytime. please explain how you get the answer. thank you!​

A+50°=180°[because of straight angle]

or,A=180-50

A=130°

Now,

P=A[Alternate angle]

or, P=130°ans

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
