It's a troll-face!
Because there is no Nobel prize in mathematics.
Alfred Nobel's wife cheated on him with a mathematician, so he was just a big fat jelly-fag.

Assuming the picture is VERY wrong and that the law of reflection keeps working:
Angle of incidence equals angle of reflection
<span class="math">
\begin{equation}
\alpha
\end{equation}
[/spoiler]
the supplementary angle to the sum of them
<span class="math">
\begin{equation}
\beta=180-2\alpha
\end{equation}
[/spoiler]
so angle of incidence on upper surface, as well as angle of reflection from it, is
<span class="math">
\begin{equation}
\gamma=180-47-\alpha=133-\alpha
\end{equation}
[/spoiler]
supplementary to the sum
<span class="math">
\begin{equation}
\delta=180-2\gamma=180-266+2\alpha=-86+2\alpha
\end{equation}
[/spoiler]
so
<span class="math">
\begin{equation}
\phi=180-\beta-\delta=180-(180-2\alpha)-(-86+2\alpha)=86º[/spoiler]

OP here: sorry guys. >>3554563 was right i overlooked the standard deviation on x it was .741 not .714 wow.

>mfw all plants in the world are vegetarians who didn't want to eat meat.

mfw i turned in my differential equations for engineers exam today.

the feeling of being done with pure math classes for the rest of your life is great.

My aunty was trying to tell me that the common cold was caused by negative aura or some other shit (she also believes in homeopathy). She went on for ages telling me how her homeopathy 'doctor' had told her all of this

Her face when I said, "that's bullshit, the cold is caused by the rhinovirus"

Hi /sci/
I have really difficult question for you
he who can solve it has my respect! (and some internetz too)

I'm a eurofag so all the values are european values

If you have 10,4g Bi (bismuth) and you put it into H2O together with HNO3
What volume of H2O do you need?

reaction:
HNO3 + Bi + H2O -> Bi(NO3)3.5H2O + NO

Don't think its a REGULAR solution, there is more to it then the easy way...

What if paradise comes from the complete urbanization of the planet and the mass mechanization of the photosynthesis process?
