Question

find the angle between the lines y=(2-3)(x+5) and y=(2+3)(x-7)​

Answer 1

Answer:

Let cost of a chair be x, then cost of table will be 40+x.

It is given that,

3(40+x)+2x=745

⇒120+5x=745

⇒x=

5

745−120

=

5

625

=125 = cost of chair,

Hence, cost of table =40+x=40+125=165.

Hence, B is the right option
