Answer:
14x+8
Step-by-step explanation:
perimeter of parallelogram=2(l+b)
2(3x+9+4x-5)
2(7x+4)
14x+8
(x, y) = (10/3, -2)
x = 10/3
Answer:
22 ft
Step-by-step explanation:
To find the length of the side of a square you need to do the opposite equation for finding area.
So the equation for finding the area of a square is a - x^2, or a = x squared.
The opposite of this equation would be x = square root of 479 because the opposite operation of squared is square root.
Now you need to solve this equation
So x = square root of 479, the square root of 479 is 21.89
So the x equals 21.89 but you need to find the approximate length so you need to round. It says to round to the nearest foot so one side of the square is 22 feet long.
Answer:
Step-by-step explanation:
step 1
Find the value of w
we know that
---> by supplementary angles (form a linear pair)
substitute the given values
step 2
Find the measure of angle EPD
we know that
----> by vertical angles
substitute
substitute the value of w
step 3
Find the measure of arc DE
we know that
----> by central angle
therefore
Answer:
Angle x= 76
Step-by-step explanation:
angle DIJ = 180-107
=73
angle x =angle DJI =180-31-73
=76
both angles x and DJI are equal because they both intersect with each other.
