    You have 3 triangles: the big one, and the two smaller ones. All three are similar. You can set up ratios of corresponding sides. can you set up a ratio between 2 legs of the small triangle on the left with 2 legs of the small triangle on the right (including leg a, because you want to solve for a) ??
