x+x+48°=180°
2x+48°=180°
x=(180°-48°)/2
=66°
Short Answer x = 66
Remark

2x is the supplement of a 48 degree angle.
Supplementary angles add up to 180°

Equation
48 + x + x = 180  Collect like terms

Solution
48 + 2x = 180      Subtract 48 from both sides.
2x = 180 - 48  
2x = 132              Divide by 2
x = 66 <<<<<<<  Answer
