Answer: The 6 sections has an area of 1/72 square yards

Step-by-step explanation:

Length= area / length

Length = 1/12 ÷ 1/3 = 1/12 × 3/1 = 1/4 yards

Since the width and length are different and the 6 squares must be arranged in a 2 × 3 pattern.

The long side is 1/3 yard

1/4 ÷ 2/1 = 1/4 × 1/2 = 1/8 yard

And the width is 1/3 ÷ 3/1 = 1/3 × 1/3 = 1/9 yard

The 6 sections are 1/8 × 1/9 and each one has an area of 1/8×1/9 = 1/72 square yard

Answer:

Step-by-step explanation:

Given:

Area = 1/12 yd^2

Length = 1/3 yd

Area of a rectangle = length × width

Width = 1/12 ÷ 1/3

= 1/4

Since it is divided into 6 parts, it can be written as 2 × 3 pattern.

Since the length is the longer part, it eould be divided into 3 then the width into 2

Length of the section = 1/3 ÷ 3

= 1/9 yd

Width of the section = 1/4 ÷ 2

= 1/8 yd

Area of the section = length of the section × width of the section

= 1/8 × 1/9

= 1/72 yd^2

Hi!

We are given the information found in the picture below.

Note: The directions aren't correct, but the triangle works for this problem.

The "direct path" is the hypotenuse of this triangle.

To find this, we use the Pythagorean Theorem, where a and b are 2 legs of the triangle, and c is the hypotenuse, aka the longest side of any triangle:

a^2+b^2=c^2

We know a and b and want c

4^2+5^2=c^2

16+25=c^2

41=c^2

Therefore, c is approximately 6.403

Sidana [21]

Answer:

she turned 82 degrees.

Step-by-step explanation:

Suppose, the unknown angle is A

Now, we know that according to the sine law ,

the ratio of side of a triangle and the sine value of the angle opposite to that side is same . It says that,

if a triangle has 3 sides a,b and c and 3 angles A,B,and C and they are opposite to the sides respectively then,

a/SinA=b/sinB=c/SinC

check the image below in attachment.

From the diagram at attachment.

here , angle A is required.

given, angle C= 30

side b=89 m and c= 48 m

sin law says a/sinA=b/sinB=c/sinC

first we take , b/sinB=c/sinC

or, 89/sinB= 48/sin30

or, sinB=( 89×0.5)/48 =0.92

or, B=68

we know, in every triangle , the sum of 3 angles of a triangle is 180

then, A+B+C=180

or, A=180-B-C= 180 - ( B+C)

=180-(68+30)

or, A = 82

therefore , the required angle is 82 degree.

she turned 82 degrees.
