To get from his high school to his home, Jamal travels 5.0 miles east and then 4.0 miles north. When Shelia goes to her home from the same high school she travels 8.0 miles east and 2.0 miles south. What is the measure of the shortest distance, to the nearest tenth of a mile, between Jamals home and Shelias home?
I don't understand how to figure this one out!?
draw a diagram to find that the result is 2 similar triangles. one side of the bigger triangle is 4, and the same side of the smaller triangle is 2, so there is a 2 to 1 ratio between the triangles. you know that the bottoms of both triangles add up to 3. if there is a 2 to 1 ratio, the larger triangle's side is 2 and the smaller triangle's side is 1. use pythagorean theorem to find the hypotenuse of both triangles, (5 and root 5) and add them together
