A meter 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 meter stick and its shadow is similar to the triangle formed by the flagpole and its shadow. How tall is the flagpole?

Question

anniedavies96 · Answer

these two triangles are similar, so their ratios are equal. 
 7.7 / 1.4 = x / 1, where x = the flagpole length multiply by one and simplify x = 7.7 / 1.4
