The height of the mat off the ground is 5 / √3 feet
<h3>How to find side of right angle triangle?</h3>
The right angle triangle has an adjacent side of 5 feet.
The hypotenuse and height of the right triangle is unknown.
Therefore,
tan 30 = opposite/adjacent
tan 30 = h / 5
h = 5 tan 30
h = 5 × 0.57735026919
h = 2.88675134595
h = 2.89 feet
Therefore, it can be written in surd form as follows:
height = 5 × 1 / √3
height = 5 / √3

The unit rate is 3 gallons in 1 minute.
I hope I helped!
It's 130, any quadrilateral's angles add up to 360 and those numbers add up to 230, 360-230 = 130
The property you use to get from 4(x + 3) to 4x + 12 is the distributive property.
