To solve a non-right angled triangle you need apply the sin or cosine rule depending on what info you have. In the second video of this series, Curtin's Dr Ian van Loosen defines the sine rule and works through an example. • Dr Ian van Loosen teaches pre-calculus, calculus and linear algebra to Curtin's first year undergraduate students. He has two undergraduate degrees and a PhD in Optimal Control and Computational Mathematics. • Discover maths at Curtin: http://curtin.edu/2cysnt
