In the below figure angle abc is 69 degree, angle acb is 31 degree so find the angle bdc

Answers

Answer 1

Answer:

[tex]\angle BDC=80^{\circ}[/tex]

Step-by-step explanation:

We are given that

[tex]\angle ABC=69^{\circ}[/tex]

[tex]\angle ACB=31^{\circ}[/tex]

We have to find the angle BDC.

In triangle ABC

Sum of interior angles of triangle=180 degrees

[tex]\angle ABC+\angle ACB+\angle BAC=180^{\circ}[/tex]

[tex]69+31+\angle BAC=180[/tex]

[tex]100+\angle BAC=180[/tex]

[tex]\angle BAC=180-100[/tex]

[tex]\angle BAC=80^{\circ}[/tex]

[tex]\angle BAC=\angle BDC=80{\circ}[/tex]

Angles subtended on the same are ac are equal.

[tex]\angle BDC=80^{\circ}[/tex]

In The Below Figure Angle Abc Is 69 Degree, Angle Acb Is 31 Degree So Find The Angle Bdc

Work out the coordinates of the midpoint of AB

Answers

Answer:

a) It is clear that point A is located at x = -2, and y = -1, therefore, the coordinates of point A are: A(-2, -1)

b) We can plot the point B (-2, 4) on the grid at x = -2 and y = 4.

Please check the attached graph.

c) The coordinates of the midpoint of AB:  [tex]\left(-2,\:\frac{3}{2}\right)[/tex]        

Step-by-step explanation:

Part a)

Important Tip:

The coordinates of point A can be determined by checking the location of point A.

It is clear that point A is located at x = -2, and y = -1, therefore, the coordinates of point A are:

A(-2, -1)

Part b)

We can plot the point B (-2, 4) on the grid at x = -2 and y = 4.

Please check the attached graph.

Part c)

We can determine the coordinates of the midpoint of AB using the formula

[tex]M.P_{AB}=\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

In our case, we have:

A(x₁, y₁) = A(-2, -1)

B(x₂, y₂) = B (-2, 4)

so substituting [tex]\left(x_1,\:y_1\right)=\left(-2,\:-1\right),\:\left(x_2,\:y_2\right)=\left(-2,\:4\right)[/tex] in the formula

[tex]M.P_{AB}=\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

            [tex]=\left(\frac{-2-2}{2},\:\frac{4-2}{2}\right)[/tex]

Refine

            [tex]=\left(-2,\:\frac{3}{2}\right)[/tex]

Therefore, the coordinates of the midpoint of AB:  [tex]\left(-2,\:\frac{3}{2}\right)[/tex]

Find three consecutive even integers such that the sum of the smallest and the largest is 36.

Answers

Answer:

Step-by-step explanation:

The consecutive even integers are (2n-2), (2n), and (2n+2), where n is an integer.

(2n-2) + (2n+2) = 36

4n = 36

n = 9

(2n-2) = 16

(2n) = 18

(2n+2) = 20

Answer:

the area of the shape is 7.14

Step-by-step explanation:

First, find the area of the square:

2 in x 2 in = 4 in

then to find the area of the semi- circles add them together to make a circle

To find the area of the circle, use:

pi x radius^2  

Since the diameter is 2 divide the diameter by 2 to get radius  

3.14 x 1^2 = 3.14

The circle is 3.14 plus 4 ( the square ) = 7.14

Answers

Answer:

26

Step-by-step explanation:

f(x) = -9x + 8

f(-2)

______________

When we have a function f(x), x can be plugged in with anything, when plugged, the equation the function f(x) is tied too will also have x replaced with the value.

Therefore, if f(x) equals f(-2), -9(-2) + 8

Multiply :

-9(-2) + 8

A boat traveled 240 miles downstream and back. The trip downstream took 12 hours. The trip back took 24 hours. What is the speed of the boat in still water? What is the speed of the current?

Answers

Answer:

rate boat = 15 mph

rate current = 5 mph

explanation:

d = r * t

t = d/r

240 / (r_boat + current) = 12       Multiply both sides by r_boat + r_current.

240 = 12(r_boat + current)

240/ (r_boat - current) = 24       Multiply both sides by r_boat - r_current

240 = 24*(r_boat - current)    

Since the distances are the same in both equations, you can equate the right side of each.

12 (r_boat + current) = 24(r_boat - current)     Divide by 12

r_boat + current  = 2 (r_boat - current)             Remove the brackets.

r_boat  + current = 2*r_boat - 2* current          add 2 currents to both sides

r_boat  + 3currents = 2*r_boat                          Subtract r_boat both sides

3 currents = r_boat.

240 = 12*(r_boat + current.                               Divide by 12

20 = r_boat + current                                        Put 3 currents in for r_boat

20 = 3currents + 1 current                                Combine

20 = 4 currents                                                  Divide by 4

5 = current

The rate of the current = 5 miles / hour

3 currents = r_boat

3*5 = rate_boat

15 = rate of the boat

What is her monthly payment if she must pay $8.78 per $1,000?

Answers

Answer:

The correct option is a.

Step-by-step explanation:

It is given that Nell's mortgage is $50,150 at 10 percent for 30 years and she must pay $8.78 points per $1,000.

EMI on $1000 is $8.78, so EMI on $1 is

EMI on $1 = 8.78/1000 = 0.00878

EMI on $50150 is

EMI on $50150 = 0.00878 x 50150 = 440.317 = 440.32

Therefore the correct option is a.

Which expression is the same as 54? The Great DebateOn September 26, 1960, seventy-four million viewers tuned in to watch a historic duel: the first televised presidential debate. The candidates were a young, relatively unknown Massachusetts senator named John F. Kennedy and the more experienced incumbent vice president, Richard M. Nixon. Although historians note that the candidates were equally skilled speakers, the differences in their televised performances were considerable. Viewers thought that Nixon, who had recently been hospitalized for an injury, appeared sallow and sweaty; by contrast, Kennedy looked handsome and relaxed. As Kennedy spoke, he fixed his gaze on the camera to address at-home viewers. On the other hand, Nixon directed his responses to reporters off camera, which made him seem cold and distant to television viewers. The differences in their appearances had a dramatic effect. Some people even recall that when they listened to the debate on the radio, they thought that Nixon had won, whereas when they saw clips on TV, they thought Kennedy was the better debater.What is the main idea of the passage?
