What are the missing parts that correctly complete the proof?

1) QA is the bisector of ∠PQR Given

2) m ∠ PQA = m ∠ RQA Definition of Bisector

3) ∠QXA and ∠QYA are right Given

4) m ∠QXA = m ∠ QYA All right angles are congruent

(Also, since m ∠QXA = 90 degrees and m ∠QYA = 90 degrees, you can say Transitive Property here)

5) QA = QA Reflexive Property

6) ΔQXA = ΔQYA AAS Congruence

(Angle - Angle - Side, with QA in common in both triangles)

7) AX = AY CPCTC

(Corresponding parts of congruent triangles are congruent)

8) A is equidistant Definitiion of equidistant

16

step-by-step explanation:

2 x 40 = 80

80/5

= 16

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.
