Which right triangle trick would you use to find the angle formed by a ladder and the ground, if you know the length of the ladder, and how far the base of the ladder is from the base of the house?
Inverse trig
400
Which is the only inverse trig function that will take an input that is greater than one?
arctan or tan-1 . The ratios for arccos and arcsin always have to be less than 1, because hypotenuse goes on the bottom of the fraction. Hypotenuse is always the longest side of a right triangle.
