14) Since f=5, f + 69 = 74
15) Since w = 23, w + 45 = 68
we know that
Perimeter of a triangle is equal to
P=a+b+c
where
a,b and c are the length sides of the triangle
<u>Find the perimeter of the triangles</u>
<u>Triangle N 1</u>
P=(x-2)+(x)+(3x+1)-------> P=5x-1
<u>Triangle N 2</u>
P=(2x-5)+(x+4)+(6x-7)------> P=9x-8
equate the perimeters
5x-1=9x-8--------> 9x-5x=-1+8-------> 4x=7
x=7/4------> x=1.75
therefore
the answer is
x=1.75
Answer:
A=500
Step-by-step explanation:
for mylar for polygon Area =ap/2
where a =apathem,p =perimeter
A=10*100/2
1000/2
500=a
the perimeter is the square of all the sides of the given polygon =10 sides =100
