You can put this solution on YOUR website!
yes there is and it involves trig.
The angle between the post and the ground is 90 degrees. We know that the distance between the two posts is 8 feet. We also know that from the of one post to bottom of second post is at a 35 degree angle. So we know the opposite side from the angle is 8 feet long and we are trying to find the hypotinues of the triangle. So we need to use sine here, and the equation we need is:
sin 35 = 8/x
I will leave you to solve for x but you will get an answer of 13.947 ft.
