Answer 1

1

a and d are supplementary angles, forming a line or adding to 180 degrees, so

d =180 - 120  = 60 degrees

2

f and h are called vertical angles, which are congruent.

h=70 degrees

3

c and f are supplementary.  I think they're called consecutive angles.  

f = 180 - c = 70 degrees

4

b and c are supplementary, c and g are congruent so

g = 180 - b = 120 degrees
