How do you do this

Use SOHCAHTOA to find them.

SOH = Sin equals Opposite over Hypotenuse
CAH = Cos equals Adjacent over Hypotenuse
TOA = Tan equals Opposite over Adjacent

>How do you do this

You hold your phone awkwardly while you take the picture so that it's confused about which way is up.

>>285521

Since it's all right triangles, Remember that A^2+B^2=C^2 so you really only need to figure out two of the sides before the problem turns into a basic equation.

>>285521

Any right triangle with a 45 degree corner is a perfect right triangle. Those are the gimmes in which Side A and Side B are identical.

>>285521

IF a right triangle has a 45 degree angle, then both sides that aren't the hypotenuse are the same length. From there do pythagorean theorem.

For others, use SOH CAH TOA

sin(angle)=x/given hypotenuse

and solve
