Every straight line can be written in the form y=mx+c.(If they seem completely unfamiliar with concept):M is known as the gradient of the line, which says how steep the line is. The bigge...

By the sine rule, sin^-1(5/13)=22.6 degrees.Equally, by the cos^-1(12/13)=tan¹(5/12)=22.6 degrees.

In order to do that, and this only works for right angled triangles, is using the sine, cosine, and tangent rules. An easy way to remember this is by using the acronym SOH, CAH, TOA that my teacher taught...
