Question

I need help with #11 and #17 PLEASE​

Answer 1

Answer:

11.   ∠B    ∠ABC     ∠CBA     ∠2

17.    QR = 12

Step-by-step explanation:

11.   ∠B    ∠ABC     ∠CBA     ∠2

17.    Given:  PS = 18     PR = 15      PQ ≅ RS

       It would be good if you could draw a picture for yourself

So, RS  = PS - PR

             = 18 - 15 = 3

       RS = PQ = 3

        QR = PS - RS - PQ

              = 18 - 3 - 3

              = 12
