27.6 dollars because if there are 5 small and 7 small that means that 5 plus 7 is 12 and 12 times 2.30 is 27.6
4is thex the yintercept is -8
The half angle formula is:
sin x/2 = +/- √ (( 1-cos x ) / 2 )
5π/12 = 5π/6 : 2
sin 5π/12 = +/- √(( 1 - cos ( 5π/6)) / 2 )
cos 5π/6 = cos 150° = -√3/2
≈ 0.966 ( this is sin 5π/12 )
The garden with the largest area is garden b with an area of 6000 feet squares
<h3>What is the area of a rectangle?</h3>
The area of a rectangle is simply known as the number of unit squares that can fit into the rectangle.
The formula for calculating the area of a rectangle is written thus;
Area of a Rectangle = (Length × Breadth)
<h3>How to determine the area</h3>
Using the formula:
Area of a Rectangle = (Length × Breadth)
For garden a;
Length = 25 feet
Breadth = 120 feet
Substitute the values into the formula
Area of garden a = 25 × 120 = 3000 feet squares
For garden b;
Length = 50 feet
Breadth = 120 feet
Substitute the values into the formula
Area of garden b = 50 × 120 = 6000 feet squares
Therefore, the garden with the largest area is garden b with an area of 6000 feet squares.

Answer:
The correct option is C) x + y + z = 180 degrees
Step-by-step explanation:
Consider the provided information.
It is given that four r, x , y and z.
If x , y and z are the interior angle then,
According to the Angle sum property of triangle: The sum of three interior angles of triangle is 180°.
Therefore, the sum of x , y and z must be equal to 180 degrees.
Hence, the correct option is C) x + y + z = 180 degrees
