Cory is hiking up a hill with a constant slope. The double number line shows that after Cory hikes 3km, his elevation is 120m.

y do u put "subscirbe to ence" on a app for ppl who need with their work?

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.
