Help!
I know this isn't math but there isn't an option for photography available.

The famous documentary photographer Dorothea Lange once said, “A documentary photograph is not a factual photograph per se. It is a photograph which carries the full meaning of the episode.” What did she mean by this? Can photographs convey a larger meaning than what is present in the photograph itself? Why or why not?

the sum of all the angles in a triangle are equal to 180

so you can add   the 3 given angles together to equal 180:

5y + 2y + 2y = 180

or since all three angles have the same letter, combine the 3 angles to equal 180:

9y = 180

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.
