Question

find the value of the unknown angles x in the following​

Answer 1

Answer:

2a)45+55+x=180

x=180-100

x=80

2b) 72+32+x=180

x=180-104

x=76

2c) 90+34+x=180

x=180-124

x=56

3a) 45+60+y=180

y=180-105

y=75

x+y=180(linear pair)

x+75=180

x=180-75

x=105

3b)80=y(opposite angle)

y=80

x+y+x=180

2x+80=180

2x=80

x=40

x+y+x=180

x+80+40=180

x=180-120

x=60
