Ameter stick casts a shadow 1.4 m long at the same time a flagpole casts a shadow 7.7 m long. the triangle formed by the meterstick and its shadow is similar to the triangle formed by the flagpole and its shadow. how tall is the flagpole?

Right triangle lmn has vertices l(7, –3), m(7, –8), and n(10, –8). the triangle is translated on the coordinate plane so the coordinates of l’ are (–1, 8). (x, y) → (x + 6, y – 5) (x, y) → (x – 6, y + 5) (x, y) → (x + 8, y – 11) (x, y) → (x – 8, y + 11)
