The midpoint of segment AB is (4, 2). The coordinates of point A are (2, 7). Find the coordinates of point B.

erastovalidia [21]

Answer:

<h3>The option B) is correct</h3><h3>Therefore the coordinate of B $(x_2,y_2)$ is (6,-3)</h3>

Step-by-step explanation:

Given that the midpoint of segment AB is (4, 2). The coordinates of point A is (2, 7).

<h3>To Find the coordinates of point B:</h3>

Let the coordinate of A be $(x_1,y_1)$ is (2,7) respectively
Let the coordinate of B be $(x_2,y_2)$
And Let M(x,y) be the mid point of line segment AB is (4,2) respectively
The mid-point formula is

Now substitute the coordinates int he above formula we get
$(4,2)=(\frac{2+x_2}{2},\frac{7+y_2}{2})$
Now equating we get

$4=\frac{2+x_2}{2}$ $2=\frac{7+y_2}{2}$

Multiply by 2 we get Multiply by 2 we get

$4(2)=2+x_2$ $2(2)=7+y_2$

$8=2+x_2$ $4=7+y_2$

Subtracting 2 on both

the sides Subtracting 7 on both the sides

$8-2=2+x_2-2$ $4-7=7+y_2-7$

$6=x_2$ $-3=y_2$

Rewritting the above equation Rewritting the equation

$x_2=6$ $y_2=-3$

<h3>Therefore the coordinate of B $(x_2,y_2)$ is (6,-3)</h3><h3>Therefore the option B) is correct.</h3>

In triangle ABC, a = 3, b = 5, and c = 7. Find the approximate value of angle A.

Lady bird [3.3K]

Answer:

21.8° (22° to the nearest degree)

Step-by-step explanation:

Using cosine law:

a² = b² + c² - 2bc(cosA)

3² = 5² + 7² - 2(5)(7)cosA

cosA = 13/14

A = 21.7867893

Approximately angle: 22°

Elanso [62]

If you would like to know if 3 pounds is bigger than 50 ounces, you can calculate this using the following steps:

1 pound = <span>16 ounces</span>
3 pounds = 48 ounces < 50 ounces

The correct result would be: No, 3 pounds is less than 50 ounces.
