Step-by-step explanation:
7/20
=0.35
35%
=35/100
=0.35
Hence, 7/20=35%
Answer:
135°
Step-by-step explanation:
this is a cyclic quadrilateral, so the sum of opposite sides are 180
hence,
3x+6 + x+2 = 180
4x = 180 - (6+2)
4x = 172
x = 172/4
x = 43
therefore, m∠A is :
3(43) + 6
= 129 + 6
= 135°

The length is gonna be 89 ft
72+72+89+89=322 ft
Answer: The artist used 8.6 inches more of silver wire
Step-by-step explanation:
Perimeter of the square
P = 4*a
P = 4*a = 40 in
a = 10 in
Each side of the square has a length of 10 in
The diameter of the circle is equal to the length of the side of the square
Diameter = 10 in
Perimeter of the circle
P_c = 2*π*radius = π*diameter
P_c = (3.14)*10 in = 31.4 in
Inches of silver wire (square) = 40 in
Inches of copper wire (circle) = 31.4 in
40- 31.4 in = 8.6 in
