a) 20 + 75 + x = 180
95 + x = 180
x = 85
b) x + 36 = 90
x = 54
c) 130 + 2x = 180
2x = 50
x = 25
los angulos valen 25
d) 114 + 66 + 92 + x = 360
272 + x = 360
x = 88
el angulo es 88
e) 105 + 105 + 2a = 360
210 + 2a = 360
2a = 150
a = 75
A)
20+75+x = 180

B)
130+x+x =180
C)
36+x = 90
D)
114+66+92+x = 360
272+x = 360
E)
105+105+a+a = 360
