Answer: 16π
Step-by-step explanation:
First, solve for total area:
A = πr^2
A = π(8^2) = 64π
Then, find 1/4 of the area of the whole (since this is only a quarter circle)
A/4 = (64π)/4 = 16π

Answer:
x=85
Step-by-step explanation:
let's angle c be x
39+56+x=180
95+x=180
x=180-95
x=85
Answer:
85 degrees
Step-by-step explanation:
In similar triangles, corresponding angles are congruent, or have the same measure.
Therefore, angle B must also be 56 degrees. In a triangle, there are 180 degrees.
A+b+c=180
39+56+c=180
c=85 degrees.

A garden is designed in the shape of a rhombus formed from 4 identical 30°-60°-90° triangles. The shorter distance across the middle of the garden measures 30 feet. What is the distance around the perimeter of the garden? 120ft.
The perimeter of the rhombus is P = 120 feet
What is the perimeter of Rhombus?A Rhombus has four sides of the same length, its perimeter can be determined using the formula Perimeter = 4a, where "a" stands for the side's length.
When the two diagonals of a rhombus are known,
The perimeter = 2√p² + q²
where 'p' and 'q' are the diagonals.
Given data ,
Let the rhombus be represented as ABCD
Let the side length of the rhombus be AB = 30 feet
And , perimeter = 2√p² + q²
And , P = AB + BC + CD + AD
Due to the four triangles' similarity, we may conclude that AC is divided at O. So, we are aware that AO = 15 feet.
In ΔAOD,
(Perpendicular/hypotenuse) = sin 30°
or, 1/2 = 15/AD
otherwise, AD = 15 x 2 = 30 ft
So, AD equals 30 feet.
Given that all of a rhombus' sides are equal and all four of its triangles are the same, we have AB = BC = CD = AD = 30 feet.
On simplifying , we get
P = 4 ( 30 feet )
So , P = 120 feet
Hence , the perimeter is 120 feet

What is trigonometric identity?The trigonometric identities is the relationship between the different trigonometric ratios.
These trigonometric identities are the basic formulae that are true for all the values of the reference angle.
For the given situation, the derivation for the tangent sum identity is given in the table below.
The derivation follows the steps,
[tex]\dfrac{sin (x+y)}{cos (x +y)}[/tex]
we know that,
sin (x + y) = sin x cos y + cos x sin y
cos (x + y) = cos x cos y - sin x sin y
Substitute;
[tex]\dfrac{sin x cos y + cos x sin y}{cos x cos y - sin x sin y}[/tex]
Divide each term by cos x cos y
[tex]\dfrac{\dfrac{sin x cos y}{cos x cos y} + \dfrac{cos x sin y}{cos x cos y} }{\dfrac{cos x cos y}{cos x cos y} - \dfrac{sin x sin y}{cos x cos y} }[/tex]
Now, [tex]\dfrac{tan x + tan y}{1 - tan x tan y}[/tex]
Hence we can conclude that the derivation of tangent sum identity taken to the expression in Step 3 to give an expression for Step 4 is option D; divide both the numerator and denominator by cos(x)cos(y).

What is the y-intercept in this equation?
6x + 3y = 24
Answer: y=−2x+8
Step-by-step explanation:
Answer:
8
Step-by-step explanation:
Let's rewrite this in slope intercept form, and isolate y on the left side. First, subtract 6x from both sides:
3y = 24 - 6x
Then divide both sides by 3:
y = -2x + 8
Now that it's in y = mx+b form, we can see that the slope is -2, and the y intercept is 8.

The area of the figure is 45 sq.mi and the perimeter is 23.5354 mi.
What is Area ?Area is the space occupied by a two dimensional object,
The area and perimeter of the given shape can be determined by dividing it into basic shapes.
here, we have,
The area and the perimeter of the shape given
= Area of the rectangle +Area of upper triangle - Area of two small triangles at the bottom
Area of rectangle = 5 mi * 9 mi = 45 sq.mi
Area of upper Triangle = (1/2) *9*3 = 27/2 sq.mi
Area of small Triangle = (1/2) * 3*6 = 9 sq.mi
Area of other small Triangle = (1/2)*3*3 = 9/2 sq.mi
Area of the figure = 45 +13.5 -9-4.5
Area of the figure = 45 sq.mi
Similarly for Perimeter = Perimeter of the rectangle +Perimeter of upper triangle -Perimeter of two small triangles at the bottom
Perimeter = 28 -(3+6+6.708) -(3+3+4.2426) +(3+9+9.486
Perimeter = 23.5354 mi
Therefore , The area of the figure is 45 sq.mi and the perimeter is 23.5354 mi.
