A small trainer and amusement park is caring passengers 1/4 of the passengers are five years old 1/2 of the passengers are six years old 1/8 of the passengers are seven years old and 1/8 or nine years old what is the expected age for one of the passengers on the train

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.

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
