    At last week's math department meeting (I teach Spec Ed at a ~600 student high school) I mentioned this fun new channel I discovered called Andy Math. This video is going in an email to the department. Thanks, these are a lot a fun.

    Edit: I don’t know if it’s possible.

    I am a designer so sometimes I use 3d model to solve these questions.
    But I also do this with my own.
    And usually the number is without any decimals so I solve it 2 times reaching same answer 15.430 and then give up to look for your explanation and get the same answer (never doubting me again)

    At one stage root 3 x root 3 becomes root 9 (then, later, 3) at another stage root 3 x root 3 immediately becomes 3. How. Odd.

    How easy

  • @inserteunnombreapropiado9079

    I did it using trigonometry.
    Let:
    x be the length of the lower side of the right.
    y be the length of the side of the square.
    z be de length of the lower side of the left.
    Using tan(), we can get this:
    x = y÷tan(60°)
    z = y÷tan(30°)
    Then, we can solve for y:
    x + y + z = 13 cm
    (y÷tan(60°)) + (y÷tan(30°)) + y = 13 cm
    y(1÷tan(60) + 1÷tan(30°) + 1) = 13 cm
    y = 13 cm÷(1÷tan(60°) + 1÷tan(30°) + 1)
    I plugged it into my calculator and gave me y = 4√3 - 3. y² = 57 - 24√3.

    If you knew x=3.93, why didn't you just square 3.93 to get 15.43. THAT would have been Brilliant!

    • @Grizzly01-vr4pn
      @Grizzly01-vr4pn Před 3 měsíci

      Because that is just a decimal approximation of the area.
      You should always try to arrive at an exact form of the solution first, rather than approximating as you go.
      3.93² actually gives you 15.44 (rounded down), not the correct rounded down approximation of 15.43
