Step-by-step explanation:
When alternate interior angles (∠ABC and ∠BCD) are congruent, it means the lines are parallel.
the area of the piece of land that is not part of the garden is
.
<u>Step-by-step explanation:</u>
Here we have , a piece of land 120 ft by 240 ft contains a circular garden. surrounding the garden, there is a circular fence that is 20 ft in diameter. We need to find what is the area of the piece of land that is not part of the garden . Let's find out:
Let's calculate area of land and circular garden , and in order to find the area of the piece of land that is not part of the garden we will subtract area of circular garden from land !
Area of Land:
Area of land is given by
⇒ 
⇒ 
⇒ 
Area of Garden:
Area of circular garden given by
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Hence , the area of the piece of land that is not part of the garden is 28,880-314 = 28,486 . Therefore , the area of the piece of land that is not part of the garden is
.
Answer: He still owns 64% of the Mr.Williams' original parking.
Step-by-step explanation:
Let x = Area of the original parking plot.
First he sold 20% of his lot to neighbor .
Sold plot = 20% of x = 0.20x [Replace 'of' by '×' and divide number by 100 to remove %]
Reminder= x-0.20x= (1-0.20)x=0.80x
Again he sold 20% of the remainder .
Sold plot = 20% of (0.80x) = 0.20 (0.80x)
= 0.16x
Remainder plot = 0.80x-0.16x= 0.64x
Percent of Mr.Williams' original parking lot does he still own = 
Hence, he still owns 64% of the Mr.Williams' original parking.
QRS = DRS + QRD
167 = x + 143 + x + 30
167 = 2x + 173
-2x = 173 - 167
-2x = 6
x = 6/-2
x = -3
DRS = x + 143
= (-3) + 143
= 140
