Answer:
a)x+67+67=180
x=180-134
x=46
b)2x+48=180
2x=180-48
2x=132
x=66
c)the value of the angle=180-(60+60)
=180-120
=60
each angle is 60;
x=x=4cm
x=4cm
d)180/3=60
x+20=60
x=30
e)70+40+x=180
x=180-110
x=70
y=4cm
f)45+45+p=180
p=180-90
p=90
g)if the remaining two angles are named y each ;
2y+24=180
2y=180-24
2y=156
y=78
then; y+24=n
78+24=n
n=102
h)180-112=68
p+68+68=180
p=180-136
p=44
i)180/3=60
180-60=t
t=120
