Answer: 1 1/4 (1 whole and 1/4)
6 1/4 = 25/4
5 = 5/1
(25/4)/(5/1) = (25/4)*(1/5)
(25/4)*(1/5)
25/20
1 5/20 = 1 1/4
Answer:
∠ A = 35°, ∠ B = 70°, ∠ C = 75°
Step-by-step explanation:
let ∠ A be x then ∠ B is 2x ( twice as large as A ) and
∠ C is 2x + 5 ( 5 more than B )
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
x + 2x + 2x + 5 = 180, that is
5x + 5 = 180 ( subtract 5 from both sides )
5x = 175 ( divide both sides by 5 )
x = 35
Thus
∠ A = x = 35°
∠ B = 2x = 2 × 35° = 70°
∠ C = 2x + 5 = 70 + 5 = 75°

Answer:
An artist use 51.9 feet of string for constructing a piece of art in the shape of rectangle
Step-by-step explanation:
Here an artist is constructing a piece of art in the shape of rectangle having length 12 feet & width of 7 feet
Since the artist wants to use string to tightly tie each vertex of rectangle to the other three vertices. Hence one string will tie in a diagonal way
Hence total length of string will be
Total length = Perimeter of rectangle + length of diagonal
Perimeter of rectangle = 2( length + width ) = 2 ( 12 + 7 ) = 2 x 19 = 38 feet
Length of diagonal given by Pythagoras theorem

Hence
Total length = Perimeter of rectangle + length of diagonal
Total length = 38 feet + 13.89244 feet = 51.9 feet
Hence an artist use 51.9 feet of string for constructing a piece of art in the shape of rectangle
