Arectangular billboard 7 feet in height stands in a field so that its bottom is 12 feet above the ground. a nearsighted cow with eye level at 4 feet above the ground stands x feet from the billboard. express θ, the vertical angle subtended by the billboard at her eye, in terms of x. then find the distance x0 the cow must stand from the billboard to maximize θ.

θ(x) =

We form rectangular triangle. Ninghty degrees angle.

Step-by-step explanation:

1) the top of the billboard is    

   7+12=19 feet above the ground

2) the eye of the cow is

  4 feet high

3) the opposite side of the triangle is

  19-4=15 feet

4) the distance between cow eye and billboard is

  "x"

5) tg (θ)=15/x

6) x=15/tg(Θ)

there is no picture

step-by-step explanation:

put up a picture so people can you

his first public project he is asked to create a small scale drawing. the garden is a right triangle with base 25m and height 30m. are you trying to solve for the last side/hypotenuse? the irrational form of the answer would be 5\sqrt{61}
