now given that

a+b=118 equation 1

and a-b=32 equation 2

by equation 1

a=118-b

now put the value of a in equation 2

(118-b)-b=32

118-b-b=32

2b=118-32

b=86/2

b=43

now put the value of b in equation 1

a+43=118

a =118-43

a=75

now we knows that

a+b+c= 180

75+43+c=180

118+c=180

c=180-118

c=62
