Answer 2

SOLUTION

21). Given, x= 2k-1 &y= k-1

Putting the value of x&y in equation:2x-3y+5=0

=)2x-3y+5=0

=)2(2k-1)-3(k-1)+5=0

=)4k-2-3k+3+5=0

=) k+6=0

=) k= -6

23).The line segment has two endpoints A and B whose length is fixed.

24). Let the angle be x.

Therefore it's supplement= 180-x

4 times its supplement = 4(180-x)

=) 720-4x

According to the given condition in the question, x= 720-4x

=) x+4x= 720(transposing -4x)

=) 5x= 720

=) x= 720/5

=) x= 144°

The angle is 144°

hope it helps ✔️
