There are many formulas to finding a side of a triangle.

Be sure to understand the differences between a right-angled triangle and an irregular-shaped triangle.

Right-angled triangle

Two sides must be known.

where ‘a’ squared is the hypotenuse of the triangle.

To find the non-hypotenuse side, the formula can be rearranged to

‘b’ can be any non-hypotenuse side.

Non-right angled triangle.

Cosine rule

Two sides and an angle must be know.

That is just a few of the formulas I have listed.
