Answer:
5/4
Step-by-step explanation:
4y = 5x Divide by 4
y = (5/4) x
To make y = kx from y = (5/4) x
k must be (5/4)
k = 5/4
I think it is b

Triangles add to 180° and there is already 100° shown inside of the triangle (30° plus 70° = 100°). 180° -100° = 80°, which is x. X and y are vertical angles, so y is also 80°. The answer is B.
It’s the 3 and for number 2 it’s 1
