How do I go about solving sin π/4 + cos π/4
Viktor [21]
Hello Shakyiagrooms. We know:

\sin(\frac{\pi}{4}) = \frac{1}{\sqrt{2}}
AND
\cos(\frac{\pi}{4}) = \frac{1}{\sqrt{2}}

By knowing this, we can set the problem up as the following:
 \frac{1}{\sqrt{2}} + \frac{1}{\sqrt{2}}
Now we can add them since they have the same denominators:
\frac{1}{\sqrt{2}} +\frac{1}{\sqrt{2}} = \frac{2}{\sqrt{2}}
Now we have to rationalize the radical denominator \frac{2}{\sqrt{2}}. We do this by multiplying \frac{2}{\sqrt{2}} by \frac{\sqrt{2}}{\sqrt{2}}

\frac{2}{\sqrt{2}}
\frac{2}{\sqrt{2}} \times \frac{\sqrt{2}}{\sqrt{2}} = \frac{2\sqrt{2}}{\sqrt{4}}
\frac{2\sqrt{2}}{\sqrt{4}} = \frac{2\sqrt{2}}{2} = \sqrt{2}
So our answer "Drum Roll Please" =
 \sin(\frac{\pi}{4}) + \cos(\frac{\pi}{4}) = \sqrt{2}

Help<br> What is the SSS postulate for triangle congruence?
Kitty [74]

Answer:

Side, Side, Side

Step-by-step explanation:

If 3 sides in one triangle are congruent to 3 sides in another triangle, then the triangles are congruent. This is called the Side-Side-Side (SSS) Postulate and it is a shortcut for proving that two triangles are congruent.

Hope this helps! <3
