Help Please!!!!!!!!!!

Answer:
27°
Step-by-step explanation:
x + 72 and 3x are co-interior angles which means they sum to 180°. We can write this as:
x + 72 + 3x = 180 - now we can simplify:
4x + 72 = 180 - simplify further by subtracting 72 from both sides:
4x = 180 - 72 → 4x = 108 → x = 108 ÷ 4 = 27°
Hope this helps!

[tex]\\ \sf\longmapsto 4x+72=180[/tex]
[tex]\\ \sf\longmapsto 4x=180-72[/tex]
[tex]\\ \sf\longmapsto 4x=108[/tex]
[tex]\\ \sf\longmapsto x=\dfrac{108}{4}[/tex]
[tex]\\ \sf\longmapsto x=27[/tex]
