To work out lengths in a (non right angle) triangle you need to use trigonometry which

consists of sine, cosine and tangent. Each of these different calculations apply to different

parts of the triangle. To remember which parts they apply to use:

SOHCAHTOA

That is: SineX=Opposite/Hypotenuse CosineX=Adjacent/Hypotenuse and TangentX=Opposite/Adjacent

As you can see each of the calculations applies to different sides of the triangle, below is a

diagram to show you where each side is on the triangle and how to find it.

Hypotenuse-always the longest side

X

Opposite-this side is opposite to

Adjacent-this side is touching/ the angle

adjacent to the angle…read more
