Since its a linear pair,
(2x+4)° + (x+23)° = 180° (Since a linear pair = 180°)
2x+x+4+23 = 180°
3x+27 = 180°
3x = 180° - 27
3x = 153°
x =153/3
x = 51
Therefore, (2x+4)° = 2*51+4
= 106°
&
(x+23) = 51+23
= 74°
Hope you understood!
The two given angles form a linear pair so their sum is 180°
(x + 23) + (2x + 4) = 180
3x + 27 = 180
3x = 153
x = 153/3
Answer: 51
