Answer:

1.) The answer is b = 6

For the first equation in order to fin out the answer we do.....

b + 8 = 14

b + 8 - 8 = 14 - 8

Find each missing angle measure
timurjin [86]

Answer: angle 1=129 degrees

Step-by-step explanation:

180 - 99 - 30 = 51

all the angles of a triangle should add up to be 180 degrees

51+99+30=180

angle 1 is supplementary to the angle that is 51 degrees so it would be 129 degrees. 180-51=129
