1) If the nirclonasses through the point (-1,-3) and the leng​

Answer 1

Answer:

Step-by-step explanatio

The measure of sides of triangle with given points are

QR = 3  unit

RT = 9  unit

TQ =    unit

Step-by-step explanation:

Given as :

The coordinate of Triangle QRT as :

Q = ( - 2 , - 1 )

R = ( 1 , 5 )

T = ( - 8 , - 4 )

Now , The Distance between the points can be measure as :

QR =

Or, QR =  

Or, QR =

Or, QR =  = 3  unit

Similarly

RT =  

Or, RT =  

Or,  RT =  

Or, RT =   = 9  unit

And

TQ =  

Or, TQ =  

Or, TQ =

Or, TQ =   unit

Hence The measure of sides of triangle with given points are

QR = 3  unit

RT = 9  unit

TQ =    unit
