Answer:
x=2 and y=3
Step-by-step explanation:
y-2=x-1
or,x-y=-1.......(1)
again,
2x+1=y+2
or,2x-y=1.......(2)
now,
solving equations (1)&(2),we get,
x=2 and y=3
Given the radius of the inscribed circle, the length of any side of the octagon (and any other polygon) is given by;
Side = 2r* tan (180/n) where r=radius and n=number of sides.
For octagon, n= 8 and radius is given by , r= 7/2 = 3.5 ft
Therefore,
Side = 2*3.5*tan (180/8) 2.8995 ft =2.9 ft.
The correct answer is A.
Answer:
1/4 square yards
Step-by-step explanation:
Remember, area equals length times width. So, that means length equals area divided by width, same with width. Width equals area divided by length. Right now, we are finding length, so the equation would be area/width
1/6/2/3=1/6*3/2 (rewriting with reciprocal)
1/6*3/2=3/12=1/4 square yards
If we check it, area equals length times width. So, 1/4*2/3=2/12=1/6.
The answer is correct!
Hope this helps and Merry Christmas :)
