I’m pretty sure B because 1/4 divided by 1/2 equals 1/2 and that the only one that has a model that has 1/2 but don’t take my word for it

They both are complementary, so their sum would be 90 degrees.
5x-12 + 4x+3 =90
9x - 9 = 90
9x = 99
x = 11

So, angle 1 = 5x-12 = 5(11)-12 = 55-12 = 43
angle 2 = 4x+3 = 4(11)+3 = 44+3 = 47

So, your final answers are: angle 1 = 43 degrees & angle 2 = 47 degrees

Hope this helps!
