WE KENS) Need Help? '0 _utorial Exercise Use an inverse trigonometric function to write 0 as a function of X. x216 Step 1 The given right triangle is shown in the figure below. A l x2-16 Observe that the lengths of the sides opposite and adjacent to the angle 0 are indicated in the gure. So, we can use the - - function to write 0 as a function of X. Step 2 Recall that if 9 is an acute angle of a right triangle, the tangent function of 9 is defined as follows. The abbreviations opp and adj represent the lengths of the sides opposite l9 and adjacent to 6, respectively. Using the above definition, express tan 6 in terms of x.
