Fill in the missing numbers along the sides of the triangle so that it contains each of the numbers from 3 through 11 exactly once. Furthermore, each side of the triangle should contain four numbers whose sum is 28.

$450

step-by-step explanation:

first, you have to multiply 150x2=300

next, you have to add 150+300= 450

is there answer choices?

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.
