I am trying to work out an angle for a right angled triangle. This is what I have so far:
Tan? = o / a
= 5 / 9
= 0.555
= 0.56 (rounded)
What would I do next to get the size of the angle?
Take the tangent inverse.......this is denonted as "arctan" or as tan-1 on your calculator
So we have
tan-1 (0.56) = θ ≈ 29.25°
