- 1What formulae do you use to find a side using the sine rule in any non right angled triangle?\[\frac{a}{sinA}\=frac{b}{sinB}\=frac{c}{sinC}\]
- 2What formulae do you use to find an angle using the sine rule in any non right angled triangle?\[\frac{sinA}{a}\]=\[\frac{sinB}{b}\]=\[\frac{sinC}{c}\]
- 3What formulae do you use to find a side using the cosine rule in any non right angled triangle?\[a^2=b^2+c^2-2bcCosA\]
