    ok the similar shapes are equiangular |dw:1363893905762:dw| the angles marked A are equal... corresponding angles in parallel lines the angles marked B are equal ... corresponding angles in parallel lines The angle marked C is common to both triangles... the side length of the larger triangle is 9 so compare the ratios of corresponding sides \[\frac{9}{6} = \frac{x}{7}\] cross multiplign gives 63 = 6x solve for x...
