Notice the tickmark on the angles, those angles are equal to each other.

now, notice the angle at the very top, the large triangle is really sharing it with smaller-inscribed triangle, and therefore is equal on both triangles.

therefore, the larger triangle, is similar with smaller-inscribed triangle by AA.

what the dickens does that mean?

\bf \cfrac{large}{small}\qquad \cfrac{4+5}{4}=\cfrac{5+x}{5}\implies \cfrac{9}{4}=\cfrac{5+x}{5}\implies 45=20+4x
\\\\\\
25=4x\implies \cfrac{25}{4}=x\implies 6\frac{1}{4}=x

The Midpoint of AB dkdldl
Nutka1998 [239]
  • The Midpoint of AB is (1,0).

Given that:

  • In line AB, where the coordinates of A is (3,1) and coordinates of B is (-1,-1).

To find:

  • The Midpoint of line AB.

So, according the question

We know that,

The midpoint M of a line segment AB with endpoints A (x₁, y₁) and B (x₂, y₂) has the coordinates M ( \frac{x_1 + x_2}{2} , \frac{y_1 + y_2}{2} ).

Now from question,

We know that the the coordinates of A is (3,1) and coordinates of B is (-1,-1) of line AB.

So, we can say that

   A is (3,1) or x₁ = 3 and y₁ = 1.

   B (-1,-1) or x₂ = -1 and y₂ = -1.

∵ The coordinates of midpoint M (X,Y)

          X = \frac{x_1 + x_2}{2}

              = \frac{3-1}{2}

              = 2/2

          X = 1.

And

          Y = \frac{y_1 + y_2}{2}

              = \frac{1-1}{2}

              = 0/2

          Y = 0.

So, the midpoint of line AB is M (1,0)

Find the slope of the line through each pair of points (6, -10) , (-15 , 15)​
dem82 [27]
<h3><u>Answer:</u></h3>

\boxed{\boxed{\pink{\bf \leadsto The \ slope \ of \ the \ line \ is \ \dfrac{-25}{21}.}}}

<h3><u>Step-by-step explanation:</u></h3>

Two points are given to us and we need to find the slope of the line . The slope of the line passing through points \bf (x_1,y_1 ) \ \& \ (x_2,y_2) is given by ,

\qquad\boxed{\red{\bf Slope = tan\theta=\dfrac{y_2-y_1}{x_2-x_1}}}

Here , the points are ,

  • ( 6 , -10 )
  • ( -15 , 15 )

\bf\implies Slope = \dfrac{y_2-y_1}{x_2-x_1} \\\\\bf\implies Slope =\dfrac{15-(-10)}{-15-6} \\\\\bf\implies  Slope = \dfrac{15+10}{-21}\\\\\bf\implies Slope =\dfrac{-1(25)}{-1(-21)}\\\\ \bf\implies\boxed{\red{\bf Slope =\dfrac{-25}{21}}}

<h3><u>★</u><u> </u><u>Hence </u><u>the</u><u> </u><u>slope</u><u> </u><u>of</u><u> the</u><u> </u><u>line</u><u> </u><u>join</u><u>ing</u><u> </u><u>the </u><u>two</u><u> </u><u>points</u><u> </u><u>is</u><u> </u><u>-</u><u>2</u><u>5</u><u>/</u><u>2</u><u>1</u><u> </u><u>.</u></h3>
