Find the midpoint of A and B where A has coordinates (2,7)<br> and B has coordinates (6,3).

Veronika [31]

Given that the coordinates of the point A is (2,7) and the coordinates of the point B is (6,3)

We need to determine the midpoint of A and B

<u>Midpoint of A and B:</u>

The midpoint of A and B can be determined using the formula,

$Midpoint =(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$

Substituting the points (2,7) and (6,3) in the above formula, we get;

$Midpoint =(\frac{2+6}{2}, \frac{7+3}{2})$

Adding the numerator, we have;

$Midpoint =(\frac{8}{2}, \frac{10}{2})$

Dividing the terms, we get;

$Midpoint =(4, 5)$

Thus, the midpoint of the points A and B is (4,5)

svet-max [94.6K]

Answer:

Using A^2+B^2=C^2

12^2+5^2=169

Hypotenuse= 13

Sin(Ø)= 5/13

Cos(Ø)= 12/13

Tan(Ø)= 5/12

csc(Ø)=13/5

sec(Ø)=13/12

cot(Ø)=12/5

Please said thanks

Select the correct answer

NemiM [27]

let f(r)=sin^3r/cos^3r

so f(-r)= (sin(-r)/cos(-r))^3

=(-sinr/cosr)^3

=-f(r)

so it is odd function

What is the value of x?

sineoko [7]

90 = 49 + x
90° - 49° = x
41 = x

I decrease it with 90 because the corner is facing. I hope the answer is right...
