Respuesta :

The straight line equals 180 degrees.
-180 minus given value (43)
180-43= 137
(4x+1)= 137
- get x by itself
4x+1=137
4x=137-1
4x= 136
x= 136/4

Answer:

x= 34

Step-by-step explanation:

(4x + 1 )° + 43° = 180° (due to linear pair)

4x+1+43 = 180

4x + 44 = 180

4x = 180 - 44

4x = 136

x = 136 ÷ 4

therefore, x = 34
