Cosine rule incorrect

questions on the starter are both inappropriate, the cosine question involves using a quadratic (swap the x and the 10cm and it's fine though) and the sine rule question is an isosceles triangle so sine rule not needed. (the exercise is good except question 4, swap the 17cm and the x to make the question work without using quadratic equations) apart from that its a good worksheet and saved me a lot of time.

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.

Thanks - as person before said, made life easier than starting from scratch.
