Answer:
0.1671 or 16.7%
Step-by-step explanation:
Original cost: $3.59
Inflated cost: $4.19
$4.19 - $3.59 = $0.60
$0.60 / $3.59 = 0.1671 ---> 16.7%
The area of the shaded triangle formed as the result of the overlap is = 62.35 inches ²
<h3>Calculation of the equilateral triangle</h3>
After folding the rectangle with length of 12 inches and width of 18 inches, an equilateral triangle was formed.
An equilateral triangle is a type of triangle where by all the three sides are equal.
To determine the value of one of the sides, CB or CD is used because the folding didn't affect these sides.
Using the formula for the area of an equilateral triangle,
A = √¾ a²
a= 12 inches
A = √¾ ×12²
A = 62.35 inches ²

Answer:
The diagonal must be 17 ft
Step-by-step explanation:
To determine the diagonal, we will use the Pythagorean theorem. That is for right triangles (which means the angle is 90 degrees)
a^2 + b^2 =c^2
where a and b are the legs and c is the hypotenuse
a = 8 ft and b = 15 ft because these are the sides of the wall and the hypotenuse will be the diagonal
8^2 + 15^2 = c^2
64+225 = c^2
289 = c^2
Take the square root of each side
sqrt(289) = sqrt(c^2)
17 =c
The diagonal must be 17 ft
Answer:
14x
Step-by-step explanation:
<em>You have two like terms (numbers with the same letter) so you are going to put those aside for a moment.</em>
<u>Add 5+7+2 </u>and you get 14.
Then, You put the unknown number (x) just beside the 14 to know you are <u>multiply</u>ing <u>x by 14</u> until you find the value.
14x <em>Is your answer</em>

Answer:
30°
Step-by-step explanation:
Area of a triangle can be found using either of the formula:
1. area = 1/2 x base x height
2. area = 1/2 ab sin c
Since we know the length of the two edges, we will use the 2nd formula:
Area = 1/2 ab sin c
Substituting the known values:
28 = 1/2 (14)(8) sin c
28 = 56 sin c
sin c = 0.5
c = 30°
