Answer:
Step-by-step explanation:
Angles at a point add up to 360°
To find x add up all the angles and equate them to 360°
That's
168 + 123 + x = 360
291 + x = 360
x = 360 - 291
x = 69°
Hope this helps you
x = 69
The sum of a circle is 360 degrees
x+ 168+123 = 360
Combine like terms
x +291 = 360
Subtract 291 from each side
x+291-291 = 360-291
x =69
