Angle b
Angle c
Angle d
Angle e
Angle f
Angle g
Use degrees.

Answer 1

160 degrees

Explanation:

starting with the 110 degrees angle. the unnamed angle to the right of the 110 degrees is simply the complement of 110 to 180 degrees = 70 degrees.

then B is actually 180 - 90 - 70 = 20 degrees

and then A is the complementary angle of these 20 degrees to 180 degrees = 160 degrees.
