C=120

2nd Triangle

A=45

B=50

C=80

Step-by-step explanation:

1st Triangle

a+120+40=180

a+160=180

A=180-160=20

B=40(alternate

interior angles)

C=c+a+b=180

c+20+40=180

C=180-60=120

2nd Triangle

b+55+45=180

b+100=180

B=180-100=80

A=45(alternate

C=c+a+b=180

c+45+80=180

C=180-125=55
