Answer:
x = 43.5°
Step-by-step explanation:
The sum of the angles around a point = 360°
sum the angles and equate to 360
x + x + 72 + 111 + 90= 360
2x + 273° = 360° ( subtract 273° from both sides )
2x = 87° ( divide both sides by 2 )
Sum of the angles around a given point is 360°.
[tex]x + x + 72 + 90 + 111 =360 \\ 2x + 273 = 360 \\2x = 360 - 273 \\ 2x = 87 \\ x = \frac{87}{2} \\ \boxed{x = 43.5°}✓[/tex]
