Answer:

x= 45°

Properties (B).

  • Angle addition postulate
  • Subtraction property of Equality

Step-by-step explanation:

Given

mPOR = x + 7,

mSOR =x+3

mPOR + mSOR = mzPOS = 100--------Apply Angle addition postulate

mPOR + m_SOR = m_POS

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

2x+10=100----------------------------------apply subtraction property of equality

2x=100-10

2x=90----------------------apply division property of equality

2x/2=90/2

x=45°
