He should buy 32 feet of fencing. I got 32 by just finding the perimeter or in other words adding 10+10+6+6 which equal 32. You would NOT do area or 10×6 because that would include that land within the fenced area and who wants 60 feet of fencing that you can't put anything in?
Good luck, hope that helped.
Answer:
B
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
y + 10 + 2y + 50 = 180 , that is
3y + 60 = 180 ( subtract 60 from both sides )
3y = 120 ( divide both sides by 3 )
y = 40 → B
I have worked out the answer to the question, I hope it helps you. Please do not forget to check if this answer if reliable, I am not always correct
