Question :-

see fig and find the missing angles

Explanation :-

1.   It is a 7-shaped polygon
    Its angle sum is 900°

⇒ 99° + 120° + 170° + 100° + 160° + 44° + x = 900°

⇒ 219° + 270° + 204° + x = 900°

⇒ 489° + 204° + x = 900°

⇒ x = 900° - 693°

⇒ x = 207°

                                            $\boxed{\boxed{\boxed{\bf{x=207^\circ}}}}}$

2.    it is 5 sided polygon  

⇒ x + x + 16° + 102° + x - 5° + 97° = 540°

⇒ 3x + 118° + 92° = 540°

⇒ 3x = 540° - 210°

⇒ 3x = 330

⇒ $x =\frac{330}{3}\ ==> \ x = 110^\circ$

                                            $\boxed{\boxed{\boxed{\bf{x=110^\circ}}}}}$
