As I read her the above quotes... she said, "WHAT!?!?!" Thanks Drain & Nixer, she's aggravated at someone other than me today!
tell her not to take it personal ive been aggravting ppl since 1977 lol
48/2(9+3) = ?

Lol, gnoles, I capped at an 8th grade teacher for my example, so your wife doesn't count!
Try this... Solve for x
Anyone know trig?

i.e. the long leg would be 5. if the 3 and 4 side make a perfect 90.
the 31 degree leg would be longer than the other.
side x should be 10.
unless im just jacked tonight.
thats not the way they want you to do it though.

oh waint thats not right either because its a 31 degree angle, but if its 31 then the other cannot be 90 degrees!
they thought of my rule. those cheaters!
perhaps this would help Trigonometric Identities and Formulas

assuming you can have a 'bent' triangle (given your sketch isn't exact lines, I'm going to presume you have a 'bent' hypotenuse with a linear line of 12 units?)
sin(31)= (x/12) therefor 12*Sin(31)= 6.18 units
can also use (180-90-31)= 59 for missing angle. thus Cos(59)=(X/12) therefor 12cos(59)= 6.18 units
all assuming angle was given in degrees.
could also do law of sines or cosines.

Only one angle is neccessary. And lol I drew that on my phone. What you do is sin(31) = x over 12. Multiply both sides by 12... 12*sin31= 6.18

That only works in pythagorean triples...
How so? If one is 31, and the other is 90, then the unmeasured one is 59, and yes, all in degrees.

Kinda seems like the equation is written in a way to cause confusion and to serve as a medium for argument. Seems like brackets should have been used but then how could people nerd out

Wait how is it meant to be written? Is the 9+3 in the denominator? If not than its 288, if so its 2.

When I see equations like the one above, I read and treat it as a fraction with 2(9+3) being the denominator and 48 the numerator. Therefore the answer would be 2.
48÷2(9+3) is a totally different problem and would work out to 288....

Talking about bringing an old thread back!
The truth is that both answers are correct. The real problem isn't in the answer but the question.
An equivalent statement in English would go along these lines.
The ball hit the bat and it broke.
The bat hit the ball and it broke.
Well, what broke? The bat or the ball? We have no way of knowing what the person who wrote the statements was trying to say.
In the case of this math question we don't know if the (9+3) was intended to be in the numerator or denominator. The way the equation is written it could be either.

Insightful answer loading... please wait.
Here's my opinion:
The equation should look like this if written out;
48
-------- = 2
2(9+3)
The equation should look like this if written out;
48
-------- = 2
2(9+3)

PEMDAS had more rules than what they originally taught you. You do what's inside the parentheses first and then outside. (9+3) = (12) and 48/2 = 24. Then you will multiply them together because you are left with 24(12) = 288. Simple!
