How do I find the measure of the lettered angles using linear pair conjectures and vertical angle conjectures?

Answer:
a = 60
b = 120
c = 120
Step-by-step explanation:
A has the same angle as 60 degrees
To find b
60 + b = 180
b = 120
C has the same angle as b
So c = 120
I know I'm bad at explaining.
