Answer:
we cant make box plots on this sorry
Vertical angles are equal
2x + 40 = 8x - 32
40 + 32 = 8x - 2x
72 = 6x
72/6 = x
12 = x
2(12) + 40 = 24 + 40 = 64
8(12) - 32 = 96 - 32 = 64
so angle 1 is 64 and angle 2 is 64
Answer:
$137.45
Step-by-step explanation:
First, we need to find the area of the circular rug in square feet.
Then we will multiply that with 1.75 to get total cost.
First,
Area of Circle =
Where r is the radius (which is half of diameter)
Given, diameter = 10 feet
Radius = 10/2 = 5 feet
Now, the area (A) :
So, total cost would be:
78.54 * 1.75/sq ft = $137.45
