hi,
1 ) b = 50 ( vertically opp. angles )
180 = a + b + 60
180 = a + 50 + 60
180 - 110 = a
a = 70
2) consider another angle in the triangle to be c.
b = c ( angles opp. to equal sides )
180 = a + b + c
180 = 50 + 2b ( b = c)
180 - 50 = 2b
130/2 = b
b = c = 65
3)a = 180 - 80
a = 100
180 = a + b+ c
180 = 100 + b + 35
180 - 135 = b
45 = b
hope it helps.....

hope it helps.....
