Use the diagram below to create a paragraph proof for the statement: "The sine and cosine of complementary angles are equal"

Answers

Answer:

Complemenraty angles are two angles with sum of 90°. In the given triangle ∠A and ∠B are complementary.

Now, the sine and cosine

sine = opposite side/hypotenusecosine = adjacent side/hypotenuse

Find the sine of ∠A and cosine of ∠B

sin A = BC/ABcos B = BC/AB

Since right sides are equal, left sides are equal too

sin A = cos B

Similarly, we can show that

sin B = cos A

Answer:

perimeter: 73.81 inarea: 284.955 in²

Step-by-step explanation:

You want to find the perimeter and area of a sector that is 3/4 of the circle. The perimeter will be the sum of twice the radius and the length of the arc. The area will be 3/4 of the area of the full circle.

__

Perimeter

The length of a circular arc is ...

  s = rθ . . . . . where θ is the central angle in radians

  s = (11 in)(3/2π) . . . . . . . a 3/4 circle has a central angle of 3/2 radians

  s = (11 in)(3/2)(3.14) = 51.81 in

When we add the two radii to this, we get a total perimeter of ...

  P = 2r +s = 2(11 in) +51.81 in = 73.81 in . . . . perimeter of the figure

__

Area

The area of a sector is given by the formula ...

  A = 1/2r²θ . . . . . where r and θ are the radius and central angle (in radians)

  A = 1/2(11 in)²(3/2π) = (1/2)(121 in²)(3/2)(3.14)

  A = 284.955 in² . . . . area of the figure

Answers

Answer:

  see attached

Step-by-step explanation:

An amortization schedule is conveniently prepared using a spreadsheet. It has the formula built in for computing the payment value.

__

The amount of the payment going to interest is the product of the outstanding balance and the monthly interest rate (=6%/12). In the attached, the amount of interest due is rounded to cents. The remaining amount of the payment reduces the outstanding balance.

The attachment shows the payment calculation and the amortization schedule for the first 5 payments.

15. Given a rectangle ABCD with AD 12. The diagonals AC and BD intersect at point O such that
mZDOC = 30°. Find the area of the rectangle.

Answers

Answer:

To find the area, we need to find the side length AB (and DC).

The easiest way to approach this is to draw a sketch with all the given information (see attached).

As point O is the center point of the rectangle, we can draw a horizontal line from point O to the center point of BC (point M on the diagram) and create a right triangle.  We can then use the Sine rule to find the shortest leg of the triangle (marked as x on the diagram).  This will be half of the side length AB, and so to find the side length, simply multiply it by 2.

To find the missing angles of the right triangle:

m∠COM = (180° - 30°) ÷ 2 = 75°

m∠OCM = 180° - 90° - m∠COM = 90° - 75° = 15°

Sine rule

[tex]\sf \dfrac{a}{sinA}=\dfrac{b}{sinB}=\dfrac{c}{sinB}[/tex]

(where A, B and C are the angles and a, b and c are the sides opposite the angles)

[tex]\implies \dfrac{x}{\sin(15)}=\dfrac{6}{\sin(75)}[/tex]

[tex]\implies x=\sin(15)\cdot \dfrac{6}{\sin(75)}[/tex]

[tex]\implies x=12-6\sqrt{3}[/tex]

As AB = [tex]2x[/tex]

[tex]\begin{aligned} \implies AB & =2x\\ & =2(12-6\sqrt{3})\\ & =24-12\sqrt{3}\end{aligned}[/tex]

Now we have both side lengths of the rectangle, we can easily calculate the area.

Area of a rectangle = width × length

                                = (24 - 12√3) × 12  

                                = 288 - 144√3

                                = 38.5846837...

4 Alfie did a survey to find which soup was most popular.
The choices were:

mushroom
A quarter of the children chose chicken soup.
Four times as many children chose tomato soup as chose mushroom soup.
Alfie makes a pie chart to show this information.
What angle should he use for the children who chose tomato soup?

Answers

The angle that would be used to show the number of children that chose tomato soup on a pie chart is 200°.

What angle reprsents the children that chose tomato soup?

A pie chart displays data in a circle. The sum of angles in a pie chart is 360 degrees

The first step is to determine the angle that would be used for children that chose chicken soup:  1/4 x 360 = 90

Remaining angle = 360 - 90 = 250 degrees.

Angle that can be used to represent the children that chose tomato soup: 4x + x = 250

5x = 250

x = 50

50 x 4 = 200 degrees

if a sum of money increased by 1/5 of itself every year and in 5 years amounts to Rs.8546,find the sum

Answers

Answer:

Answer :

Given  : If a sum of money amounts to Rs 2200 in 5 years

Let sum of money =  x

And as given : The interest is 3838 of the principal . So we get

x ( 3838 ) = 2200 - x

3x  =  17600 - 8x

11x  =  17600

x   =  1600

So, Sum of money  =  Rs . 1600

Then interest =  2200 -  1600 =  Rs . 600

Let Rate of interest  = r  %

And we know Simple interest  = P × r × t100P × r × t100 , So we get

⇒1600 × r × 5100 =  600⇒16× r × 5100 =  6⇒80r  =  600⇒r = 60080 = 152 =  712%⇒1600 × r × 5100 =  600⇒16× r × 5100 =  6⇒80r  =  600⇒r = 60080 = 152 =  712%
