The rise from the ground by the skateboard is 5.5 inches
<h3>How to determine the height above the ground?</h3>
The length of the skateboard is given as:
Length (l) = 18 inches
The angle of elevation (x) is
x = 17∘
Represent the height with h.
The value of h is calculated using the following tangent ratio:
tan(x) = h/l
Make h the subject
h = l * tan(x)
Substitute known values
h = 18 * tan(17)
Evaluate
h = 5.5
Hence, the rise from the ground by the skateboard is 5.5 inches

Hi there! The answer is 400 square yards.
When the total fencing around a square field is 80 yards, that means that the fencing on one side of the square field is 80 / 4 = 20 yards (Since a square field has 4 sides which are equally as long as every other side).
When the side of the field is 20 yards, the area (which is width * length) equals 20 yards * 20 yards = 400 square yards.
I think that it’s 17 not a good
