Answer:

b/x = (x + y)/b

where c = x + y then

b/x = c/b

Explanation:

Considering the larger of the three triangles the image represents,

b and a in light of the angle A form by both sides (the angle opposite the side a) would have a relationship

Cos A = x/b

hence b/x = 1/Cos A

Considering the largest triangle,

Cos A = b/(x +y)

hence,

(x + y)/b = 1/Cos A

as such,

b/x = (x + y)/b
