Answer:
100° is the value of angle x.
Step-by-step explanation:
Given irregular hexagon with different measure of the angles.
To find = ∠x = ?
Solution :
Sum of all angles of hexagon is equal to 720°.
[tex]x+90^o+120^o+156^o+145^o+(x+9)^o=720[/tex]
[tex]2x+529^o=720^o[/tex]
[tex]2x=720^o-520^o[/tex]
[tex]2x=200^o[/tex]
[tex]x=\frac{200^o}{2}=100^o[/tex]
100° is the value of angle x.
