Step 2 Recall that if 0 is an acute angle of a right triangle, the sine function of 0 is defined as follows. O sin(0) = _ hyp opp O sin(0) = opp hyp Terrific! The abbreviations "opp" and "hyp" represent the lengths of the side opposite 0 and the hypotenuse, respectively. Step 3 Using the above definition, express sin(0) in terms of x. Simplify your answer. X - 4 sin(0) = - X2 - 16 X - 4 x - 4 x - 4 ( x + 4 ) 1 x +4 x+4 Step 4 Finally, use the equation sin(0) = 1 x+ 4 and the definition of inverse sine function to write 0 as a function of x. 0 : X Submit Skip (you cannot come back)
