The bisector divides the line BC in the following ratio.
(x + 8) / 10 = (2x - 5) / 14 Cross Multiply
14(x + 8) = 10(2x - 5) Remove the brackets.
14x + 112 = 20x - 50 Subtract 14x from both sides . Add 50 to both sides
112 + 50 = 20x - 14x Collect like terms
162 = 6x Divide by 6
x = 27
Using the edge lengths already given, I calculated the height of the right side of the irregular octagon by adding the heights on the left. Since they added to 9m, then I put 9 on the edge with a missing height. To find the missing length, I subtracted the quantity of 6+6 from 18 (you can also divide 18 by 3) to get 6. Now that I know all the lengths, I can add them to get the perimeter. Since 3+3+3+6+6+6+9+18, or (3*3)+(6*3)+9+18 is equal to 54, our answer is 54.
