Bem simples. A soma tem que dar 360º por serem todos quadriláteros.
Figura 1:
98 + 103 + 90 (o ângulo reto da figura) + x = 360
291 + x = 360
x = 360 - 291
x = 69º
--------------
Figura 2:
x + x + 80 + 80 = 360
2x + 160 = 360
2x = 360 - 160
2x = 200
x = 100º
-----------------
Figura 3:
4x + 2x + 10 + 5x - 30 + x + 20 = 360
12x = 360
x = 360/12
x = 30º
