In 5 days, Lan jogged a total of 15 miles. She jogged the same number of miles each day. How many miles did Lan jog each day?

75 miles

if u do 15x5 you will get 75 and that's how many miles you will get

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
