Since it forms a "right triangle" we can apply trigonometry.
sin x = oppo/hyp
sin x = 13/20
x = sin^-1(13/20)
x = sin^-1(0.65)
x = 40.5
rounded to nearest degree
x = 41 degrees


Hope this helps! :)

Let f(x)=x+3 and g(x)=1/x. The graph of (f*g)(x) is shown below.
Vlad [161]
For this case we have the following functions:
 f (x) = x + 3

g (x) = 1 / x When composing the functions we have:
 (fog) (x) = f (g (x))

 Substituting values we have:
 (fog) (x) = ((1 / x) +3)

 Rewriting:
 (fog) (x) = 1 / x + 3

 The function has a horizontal asymptote at y = 3.
 Therefore, the range of the function is all reals minus y = 3.
