Calculate the midpoint of the line segment with endpoints A(− 4, −5) and B(2, 3).

Answers

The midpoint should be (-1, -1) if my math is right

The midpoint of the line segment is (-1, -1).

What is midpoint of a line segment?

The midpoint of a line segment is a point that lies halfway between 2 points. The midpoint is the same distance from each endpoint.

It is obtained by averaging the x-coordinates and averaging the y-coordinates of the endpoints of the segment.

Given endpoints

A(− 4, −5) and B(2, 3)

Midpoint of the line segment formula:

Midpoint of a Line Segment : Its x value is halfway between the two x values · Its y value is halfway between the two y values.

Midpoint [tex]= (\frac{x_{1}+x_{2} }{2} ,\frac{y_{1}+y_{2} }{2})[/tex]

Midpoint = [tex](\frac{-4+2}{2} ,\frac{-5+3}{2} )[/tex]

Midpoint = [tex](\frac{-2}{2}, \frac{-2}{2} )[/tex]

Midpoint = (-1, -1)

The midpoint of the line segment is (-1, -1).

Solve for X


explain the process for this problem​

Answers

Answer:

x = 40

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

126° is an exterior angle of the triangle, then

x + 2x + 6 = 126

3x + 6 = 126 ( subtract 6 from both sides )

3x = 120 ( divide both sides by 3 )

x = 40

A rectangle’s width is one-fourth of its length. Its area is 9 square units. The equation l(l) = 9 can be used to find l, the length of the rectangle.

What is the length of the rectangle?

0.75 units
1.5 units
3 units
6 units

Answers

Answer:

6 units

Step-by-step explanation:

The formula for the area of a rectangle = Length × Width

A rectangle’s width is one-fourth of its length.

W = 1/4 × L

W = L/4

Cross Multiply

L = 4W

A = 9 square units

Hence

9 = L × W

We substitute 4W for L

9 = 4W × W

9 = 4W²

We square root both side

√9 = √4W²

3 = 2W

W = 3/2

W = 1 1/2 unit or 1.5 units

Solving for L = Length

9 = L × W

9 = L × 1.5

L = 9/1.5

L = 6 units

Therefore, the Length of the rectangle = 6 units

Which pair of triangles can be proven congruent by SAS?

Answers

The third set of triangle can be proven by SAS as both triangles have a congruent angle in between two congruent sides.

Third pair of triangles is congruent by SAS.

What is congruency?

In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other.

If any two sides and angle included between the sides of one triangle are equivalent to the corresponding two sides and the angle between the sides of the second triangle, then the two triangles are said to be congruent by SAS rule.

In the third pair, this rule is visible. Two pair of sides are equal to each other and the angles formed at the common vertex of the two sides are equal. Hence, the two triangles are congruent by SAS.
