i write everything in the exploration

Step-by-step explanation:

MN=31

KN=45

K=61°

L=119°

M=61°

CF=10

FE=15

CE=14

GD=11

QR=19

SR=24

PT=21

SQ=20

QRS=70°

PQS=53°

RPS=35°

PSQ=53°

7x-2=12x-22

-2=5x-22

20=5x

x=4

7×4-2=26 (12×4-22=26)

(2x+11)×2=8x-14

4x+22=8x-14

22=4x-14

36=4x

x=9

( (2×9+11)×2=58. 8×9-14=58. so it's correct)

(3x+5)+(9x-17)=180

12x-12=180

12x=192

x=16

( (3×16+5)+(9×16-17)=53+127=180 so it's correct)

10x-27=2x+29

8x-27=29

8x=56

x=7

10×7-27=43 (2×7+29=43)

V=180-43°=137°

Point M is the midpoint of AB. The coordinates of point A are (−7, 1) and the coordinates of M are (−2, 2). What are the coordin
notka56 [123]

Answer:

\huge{\boxed{\sf{ ( 3 , 3 ) }}}

Step-by-step explanation:

Co-ordinates of point A = ( -7 , 1 )

Co-ordinates of point M = ( -2 , 2 )

Let the co-ordinates of point B be ( x , y )

A ( -7 , 1 ) \longrightarrow ( x1 , y1 )

B ( x , y ) \longrightarrow ( x2 , y2 )

Now,

Midpoint = (\frac{x1 + x2}{2}  , \frac{y1 + y2}{2} )

⇒( -2 , 2 ) = ( \frac{-7 + x}{2}  , \frac{1 + y}{2} )

Finding the value of x :                    

⇒-2 = \frac{-7 + x}{2}

Do cross multiplication                

⇒-4 = -7 + x

⇒-7 + x = -4

⇒x = -4 + 7

⇒x = 3

Now, finding the value of y

⇒2 = \frac{1+y}{2}

Do cross multiplication

⇒4 = 1+y

⇒1+y = 4

⇒y = 4 - 1

⇒y = 3

Hence, The co-ordinates of point B = ( 3 , 3 )

Hope I helped!

Best regards!
