In the figure above b is the midpoint of ac. solve for the length of ab.

Since it's a midpoint, you can say that 5x-6=2x ; after subtracting 2x and adding 6, you have 3x=6, then x=2. Plug two back into AB (5x-6) and you get 5(2)-6, or 10-6, or 4, the solution.

man its nopq i just guessed and got it right so uhh

g00d lucc

step-by-step explanation:

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.
