1. what is the value of x? identify the missing justifications.
m_pqr = x + 7, mzsor = x+3, and mzpqr + m2sqr = mzpqs = 100
drawing not to scale
mpor + m_sor = m_pos 2.
*+7+x+3 = 100
b. substitution property
2x + 10 = 100
c. simplify
2x = 90
x = 45
e. division property of equality
angle addition postulate; addition property of equality
angle addition postulate: subtraction property of equality
protractor postulate; addition property of equality
protractor postulate; subtraction property of equality

x= 45°

Properties (B).

Step-by-step explanation:

Given

mPOR = x + 7,

mSOR =x+3

mPOR + mSOR = mzPOS = 100Apply Angle addition postulate

mPOR + m_SOR = m_POS

x+7+x+3=100apply addition property of equality

2x+10=100apply subtraction property of equality

2x=100-10

2x=90apply division property of equality

2x/2=90/2

x=45°

i belive those are the ones that are under 90 degreese.

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent
