Answer:

Triangles ABE and CDE are congruent by AAS.

Step-by-step explanation:

AB ≅ DC (Opposite sides of a parallelogram are congruent.

m < AEB = m < DEC (Vertical angles).

m < ABE = m < EDC ( Alternate Interior angles).

So triangles ABE and CDE are congruent by AAS.

If two points known on the line AB in the coordinate plane is (7,15) and (18,42), calculate the following..

Ksju [112]

<u>Answer:</u>

Slope = 27/11
AB = 29.15 u

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

<u>Given :- </u>

Two points are given to us .
The points are A(7,15) and B(18,42)

<u>To Find</u> :-

The slope of the line .
The length of line AB .

We can find the slope of the line passing through the points $( x_1,y_1)$ and $( x_2,y_2)$ as ,

$\implies m = \dfrac{ y_2-y_1}{x_2-x_{1}}$

Plug in the respective values ,

$\implies m = \dfrac{ 42-15}{18-7} \\\\\implies \boxed{ m = \dfrac{ 27}{11 }}$

<u>Hence the slope of the line is 27/11 .</u>

$\rule{200}2$

<u>Finding the length of AB :-</u>

We can find the distance between them by using the Distance Formula .

$\implies Distance =\sqrt{ (x_2-x_1)^2+(y_2-y_1)^2} \\\\\implies Distance =\sqrt{ (18-7)^2+(42-15)^2 } \\\\\implies Distance =\sqrt{ 11^2 + 27^2 } \\\\\implies Distance =\sqrt{ 121 + 729 } \\\\\implies Distance = \sqrt{ 850} \\\\\implies \boxed{ Distance = 29.15 \ units }$

<u>Hence the length of AB is 29.15 units .</u>
