Question

in fig 9.37 , AB||RQ and BC||RQ and angle ABC = 60° , find angle PQR​

Answer 1

Answer:

      PQR = 120°

Step-by-step explanation:

       In parallel angles the sum of the angle is 180°. AB||RQ and BC||RQ.

       ABC = 60°

       PQR = $x$

       ABC + PQR = 180°

       60° + $x$ =180°

        $x$ = 180° - 60°

        $x$ = 120°

∴ PQR = 120°

Answer 2

Answer:

As given x and y are two non-negative integral numbers such that 2x+y=10.

So, the possible values will be (0,10),(1,8),(2,6),(3,4),(4,2),(5,0)

The maximum value of x+y=10 and minimum value of x+y=5.

∴ sum of maximum and minimum value of x+y is 15.
