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
