Answer:

we know that sum of angle a and b is 180

so a+b= 180

a= 34 (given)

b= 180-34

b= 146 degrees

Answer:

146 degrees

Step-by-step explanation:

Why?

Angle A and B together = 180 because they make up that one line and a line = 180 degrees and it says that angle A =34 so...

180 - 34 =  (B)

146 = (B)
