These two triangles are proportionate, as all the angles are the same. Since twp pf the angles from both shapes are equal, the remaining one must also be equal. Since KH = 8 and LG = 4 (both are similar), we can tell that with the similar sides of the small triangle, you multiply by 2 to get the bigger triangle's similar side. If GW = 2.5, HJ = 2.5*2 = 5. LW must be 3 in order to be half of KJ, which is 6.
