Answer:

152°

Step-by-step explanation:

<ext. + <int. = 180°

180-92= 88°

180-73= 107°

180-63= 117°

180-104= 76°

Sum of angles in an irregular polygon; (n-2)×180

where n is the number of sides

The polygon has 5 sides,

(5-2) × 180= 3 × 180

= 540°

88+107+117+76+x=540

388+x=540

x= 540-388

x= 152°
