What is the value of x? identify the missing justifications, m<PQR=x+7 , m<SQR = x+3 , and m<pqr+m<sqr=m<pqs=100

I just took the Unit 3 Lesson 4 Quiz for Geometry Connections (I'm in honors though so I'm not sure if it will be the same)

1. B) Angle Addition Postulate; Subtraction Property of Equality
2. D) Subtraction Property
3. C) 6x = 320
4. A) Symmetric Property
5. B) a. Given; b. Substitution Property; c. Subtraction Property of Equality; d. Division Property of Equality; e. Symmetric Property of Equality (Look carefully for this one. Its easy to get mixed up)
6. C) 19
7. B) 13
Hope this helped! I'm not sure if its the same for everyone, but this is what I had. If you got the answers wrong, I'm really sorry I was useless.

The only thing different for me was question 2 and 7.

2 for me is now Addition Property
7 for me now is 37. If m < 3 is 37 and its the same exact angle its also going to be 37.

REGULAR GEOMETRY ANSWERS (Not Honors):

1: (B) Angle Addition Postulate; Subtraction Property of Equality
2: (D) Addition Property
3: (C) 6x = 320
4: (A) Symmetric Property
5: (B) a. Given; b. Substitution Property; c. Subtraction Property of Equality; d. Division Property of Equality; e. Symmetric Property of Equality
6: (C) 19
7: (A) 37
This got me a 100%, hope this helps :).

For question 8 if you guys need help.

Vertical angles are congruent and if the measure of 1 of the angles is 72 degrees and straight lines equal 180 degrees you have to subtract 72 from 180 which equals 108. So the measures of the other three angles are 108, 108 and 72.

just wanna say how thankful i am for the ppl on this website ily guys thanks for helping me pass

Crazy Dudeeee is right just took the test 100% thx

the kid is right guys

thanks guys. crazy dude is right, except for the questions like random said

YO TY! CRZY DUDEEE AND RANDOM, YALL SAVED ME <3 TRUST THEM YO I GOT A 100%

100% right but make sure depending on what test you have you look at randoms responce as well.
