Question

Work out value of x

​

Answer 1

x=69 degrees

Basic fact:

all the angles in this graph will add up to 360 degrees

Explanation:

168+123

=291

360-291=69

x=69

Answer 2

x = 69

Explanation:

Sum of angles around a point = 360

i.e,

=> 168 + 123 + x = 360

=> 291 + x = 360

=> x = 360 - 291

=> x = 69
