Brainpower for the one who solves this first and if it's correct

thxx A is the correct answer

Step-by-step explanation:

If you need the equation, tell me in the comments, and i'll edit this answer and write the solution and how i found it :)

Step-by-step explanation:

Let the amount is x.

Sum up the shares to get full amount:

Correct choice is D

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.

step-by-step explanation:

no solution.
