Answer:
2x-y-1=0
Step-by-step explanation:
A(4,7)
B(2,3)
(y-ya)/(yb-ya)=(x-xa)/(xb-xa)
(y-7)/(3-7)=(x-4)/(2-4)
(y-7)/-4=(x-4)/-2
(7-y)/4=(4-x)/2=2(4-x)/4
so 7-y=2*4-2x
y=-8+2x+7
2x-y-1=0
Answer:
74 feet and 6 feet
Step-by-step explanation:
Mentioned that
The Length of the dog park is = (8x + 2)............(i)
And,
The Width of the park is = (2x -12)..................(ii)
Perimeter = 160 feet
Now here we use the perimeter formula which is
Perimeter is
= 2 (length + width)
160 = 2 (8x + 2 + 2x - 12)
160 = 2 (10x - 10)
160 = 20x - 20
180 = 20x
x = 9
Now put the x value into the equation 1 and equaton 2
For the equaton 1, the length us
= 8x + 2
= 8(9) + 2
= 74 feet
And, the width is
= 2x - 12
= 2(9) - 12
= 18 - 12
= 6 feet
Using the concept of supplementary angles, it is found that the measure of angle B is of 135º.
--------------------------------
- If two angles are supplementary, the<u> sum of their measures is of 180º</u>.
- A and B are supplementary, thus:
- The measure of angle A is 1/3 of the measure of angle B, thus:
Replacing in the equation for the sum:
The measure of angle B is of 135º.
