Terrible resource: Cosine rule is quoted incorrectly Second example is just an isosceles triangle which makes the Sine rule redundant Some questions lead to forming a quadratic in x, only solvable by the quadratic formula...surely not what was intended.

'c² = a² + b² - 2abcosA' should be 'c² = a² + b² - 2abcosC'!

The triangles are not right-angled because the whole point of the sine and cosine rule is to work out sides/angles of non-right-angled triangles.
