Question

?????????????????????

Answer 1

Sum of the angles around a given point is 360°.

`x + x + 72 + 90 + 111 =360 \\ 2x + 273 = 360 \\2x = 360 - 273 \\ 2x = 87 \\ x = (87)/(2) \\ \boxed{x = 43.5°}✓`

★ x=43.5° is the right answer.

Answer 2

x = 43.5°

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 )

x = 43.5°
