Can someone please help me????? Please I'm not good with Geometry
Otrada [13]

The hurdle and runner form a right triangle (see attached picture) such that

sin(30°) = <em>h</em> / (5 ft)

and

cos(30°) = <em>x</em> / (5 ft)

where <em>h</em> is the height of the hurdle and <em>x</em> is the horizontal distance from where the runner jumps to the hurdle. So

<em>h</em> = (5 ft) sin(30°) = 5/2 ft = 2.5 ft

<em>x</em> = (5 ft) cos(30°) = (5√3)/2 ft ≈ 4.33 ft

Your garden has a perimeter of 36 feet. what is the length of missing side.​
taurus [48]

Answer:

I think the answer is 3 for 1 length side. And in you need 12 for both length sides. So the total is 36 and one side is 12. Since it's a rectangle,you now know two side lengths since they are the same,just opposite from each other. So 12 + 12 = 24. You do 36 – 24 because you need to get the total number for length which is 12. 12 divided by 2 is 6 which is one length side. You can check by doing 6 + 6 + 12 + 12 and you get 36.

Hope this helped!
