Complete the following proof on page 239 #13 on the attached pdf

Step-by-step explanation:

Statements                             Reasons

1. ∠N ≅ ∠S                           Given

2. ∠NQT ≅ ∠SQR                Theorem: Vertical angles are congruent

3. Line / bisects TR at Q          Given

4. TQ ≅ QR                              Definition of bisect

5. △NQT ≅ △SQR                  AAS Postulate

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
