Value of x
For an isosceles triangle two sides are equal
AB=BC
7x-3=9x-11.
11-3=9x-7x
8=2x
2x=8
x=8/2
x=4
AB =7x-3=7(4)-3=25 units
BC=9x-11=9(4)-11=25 units
AC=4x+1=4(4)+1=17 units
Answer:
x = 5
Step-by-step explanation:
Add all of the angles together. We know that the third one is 90° because it is a right triangle and the little square indicates a 90° angle.
7x + 16 + 39 + 90 = 180
Simply.
7x + 145 = 180
-145 -145
7x = 35
/7 /7
x = 5

Answer:
32 feet
Step-by-step explanation:
area of square is given by side^2
Perimeter of square is given by 4*side
_______________________________
Given
area of square = 64 sq feet
side^2 = 64
side^2 = 8^2
side = 8
thus side = 8 feet
_______________________________________
The dog pen is fenced with chain, hence chain will be fence at the edge of square and at the perimeter.
Thus, length of chain required will be same as the Perimeter of square.
Perimeter of given dog pen with side length 8 feet = 4*8 = 32 feet.
Thus, 32 feet of chain fence is required.
