Explicación paso a paso:
A)
Suma de Ángulos interiores : 180° (n - 2)
= 180 (6-2)
=180 (4)
=720
Entonces:
110 + 120 + 105 + 115 + 135 + x = 720
585 + x = 720
x = 720 - 585
x = 135°
B) Suma de Ángulos interiores : 180 (n - 2)
= 180 (5-2)
= 180 (3)
=540
142 + 98 + 90 + 130 + x = 540
460 + x = 540
x = 540 - 460
x = 80°
